You must be closely tracking your ovulation and mating with your partner accordingly. When you are eager to get pregnant, you may want to know the result asap, rather than wait until you miss your period. But can you know if you are pregnant even before you missed your period?
A missed period is the first major sign of pregnancy and a pregnancy test is the only sure way of confirming your pregnancy. However, the changes begin to happen even before the missed period. Some women might get to notice those changes.
The early signs and symptoms of pregnancy before missed period could be very similar to those of PMS, and are not usually noticeable. Having said that, each pregnancy is different and hence you might still see it coming even before the missed period!
In this MomJunction post, we tell you about the possible symptoms of pregnancy before a missed period, and whether or not you can rely on them to confirm pregnancy.
Early Symptoms Of Pregnancy Before Missed Period
While a missed period is the most prominent sign of pregnancy, there could be other bodily symptoms you experience before your period is due. Keep reading to know more about them.
1. Implantation bleeding and cramping
If you have unprotected sex during your fertile window, there is a chance that you might get pregnant. Implantation takes place when the fertilized egg attaches to the lining of the uterus. If that happens, you may experience implantation bleeding around the same time your period is due (1).
Implantation bleeding is light, and you may notice just a few drops of blood in your panty or while wiping your vagina. Therefore, you may or may not notice it.
2. Elevated basal body temperature
Basal body temperature is considered to be an indicator of ovulation. A week or so before ovulation, your basal body temperature may be around 97 to 98°F, which is the average in the pre-ovulation state (2). One to two days after ovulation, your BBT usually increases by 0.5 to 1°F and decreases after your period ends. Most women tend to feel warmer during pregnancy, but there is no evidence to suggest that this is due to high basal body temperature.
The changes in the basal body temperature are subtle and not easy to measure, which makes it a less accurate indicator of ovulation or pregnancy.
3. Sore, tender, and heavy breasts
When you conceive, hormonal changes in the body could result in tender or swollen breasts with veins around the breast becoming visible, darkening of the areola, and tingling of the breasts. These changes can occur as early as one to two weeks after conception.
These symptoms may be similar to those of PMS but may be severe if you’re pregnant. If your period is late, and you notice breast changes along with other symptoms, take a pregnancy test to be sure (3).
Fatigue without reason may also be an early symptom of pregnancy. A spike in the levels of progesterone hormone can make you tired and sleepy all the time. Additionally, as the body begins to produce more blood to support your fetus’ growth, you will feel exhausted, especially if you don’t get enough minerals, vitamins, iron, and fluids in your diet.
If you’ve been planning to conceive, talk to your doctor and take prenatal vitamins, avoid caffeine and associated products, and sleep well to fight fatigue. Note that fatigue can also be due to other health issues such as anemia, hypothyroidism, etc., and cannot be the sole indicator of pregnancy.
Nausea or morning sickness is a classic sign of pregnancy that you may be able to notice in the early stages. It could become prominent in the initial weeks around the missed period, even before your pregnancy is confirmed. You may feel dizzy, weak, and feel like throwing up at times.
You may feel nauseous at any time of the day, but early mornings would be the worse, which is why it is referred to as morning sickness. About 50 to 80% of women experience morning nausea, but the severity may vary (4). The condition may be worse in your first pregnancy but may subside with the eventual ones.
This symptom can start anytime between two and eight weeks after conception.
6. Bloating and feeling of tightness
You may feel your tummy protruded and your pants may get tight. A heavy or bloated feeling in the stomach is a common symptom of pregnancy before missed periods (5).
Bloating could be followed by farts and burps because of the progesterone hormone, which retards your digestion. However, bloating could happen due to other indigestion issues too.
7. Food aversions
You may start disliking the foods you once loved and even become averse to them, so much so that their smell or taste might make you nauseous. Aversion to foods is common early on in the pregnancy when nausea and vomiting are present. Some may get their appetite back by the second or third trimesters, but others may have to deal with it through the pregnancy.
While the suggested cause of food aversion is an increase in the progesterone levels, there is no substantial evidence to support the theory.
Dizziness and lightheadedness could also come early on in pregnancy, due to a change in the blood volume and pressure when the blood vessels dilate in the first trimester.
9. Mood swings
Feeling moody? It could be due to the hormonal changes after conception. The variations in the hormone levels affect the neurotransmitters of the brain, resulting in enhanced emotions from spells of weeping to sudden anger outbursts (6). However, it is difficult to relate mood swings to pregnancy as women have mood swings before their period as well.
An increase in the progesterone levels can affect your digestive system. Your bowel movements get harder as the hormones cause the food to pass slowly through the digestive system. If you develop constipation before your period is due, and you’ve had unprotected sex during the fertile period, you should consider taking a home pregnancy test (7).
11. Headaches and backaches
Low blood sugar levels can cause headaches, as the brain cells try to cope up with the lower levels of sugar supply. If you have frequent headaches, then it could mean that the female sex hormones like estrogen and progesterone are preparing the womb for the baby (8).
You could also experience lower back pain as your ligaments loosen up, and your body prepares to carry the weight of the baby. Implantation cramping, bloating, and constipation can also cause backaches during early pregnancy. Your sleeping positions could be a cause of back pain.
If the pain is unbearable, go to a doctor for a proper diagnosis. Avoid taking over-the-counter painkillers, as self-medication can be harmful if you’re pregnant.
Drooling is not a common symptom, but some women may produce excess saliva if they are experiencing nausea or vomiting. Some women have this urge to spit all the time, which builds up the extra liquid in the mouth. Excess saliva is also produced to neutralize the excess acids in the stomach, causing heartburn (9).
Pregnancy-related drooling usually stops in the second trimester. You can, however, suck on something sour to alleviate drooling.
13. Excessive thirst
Women may also feel excessively thirsty in the early stages of pregnancy, usually due to an increase in the blood volume. This causes frequent urination, which in turn will make you feel thirsty again!
14. Urge to pee
An increased urge to pee is a typical pregnancy symptom that you may experience around the time when your period is due. The urge to urinate may be more during the night. This is due to excess production of the blood, owing to the many hormonal changes that occur after conception. The kidneys work to filter more blood filling up the bladder, causing you to pee frequently.
15. Shortness of breath
You may begin having shortness of breath in the first few weeks of pregnancy since your body requires more oxygen and blood to share with the growing fetus. It continues throughout pregnancy as the baby grows, and the need for oxygen and nutrients increases. Having an exercise routine, sitting in a proper posture, taking slow deep breaths, wearing loose clothes, etc., should help in regulating your breathing.
Some of these pregnancy symptoms are similar to those of PMS and may be ignored by most women. Also, a few others could be due to other medical conditions and should be checked by a doctor.
Are These Symptoms Reliable Enough To Confirm Pregnancy?
The symptoms we mentioned above are only possible indicators and not definitive signs that confirm a pregnancy. So even if you experience one or more of these symptoms, it may not always necessarily mean that you are pregnant. They are only the indicators of a possible pregnancy. Your pregnancy can be confirmed when a pregnancy test shows a positive result.
How Soon Can You Experience Pregnancy Symptoms Before A Missed Period?
You may start experiencing pregnancy symptoms within 12 to 15 days of conception (10). However, the onset of symptoms differs from one woman to another. Some women experience symptoms such as nausea, tender breasts, fatigue, sleepiness, and bloating within a week of conception.
Symptoms such as increased frequency of urination will usually occur around the time your period is due. Symptoms such as vaginal discharge, changes in the areola, and elevated body temperature appear eventually and can only be detected on close examination.
PMS Symptoms vs. Pregnancy Symptoms
PMS (pre-menstrual syndrome) and pregnancy symptoms are quite similar, but some of them (such as basal body temperature, darkening areolas, nausea, food aversions on cravings) may become more pronounced and severe in pregnancy. Taking a pregnancy test is the best way to figure out if these are signs of conception or the effects of PMS (11).
What Can Be The Other Causes For A Delayed Period?
Your period could be delayed due to many reasons other than pregnancy. They could be hormonal changes, excessive weight gain or weight loss, eating disorders (anorexia or bulimia), stress, polycystic ovary syndrome, travel, thyroid, birth control pills or drug use (12).
So, it is possible to miss your period and not be pregnant.
Is It Possible To Be Pregnant And Get Your Period?
You are unlikely to get your period if you are pregnant. But as mentioned before, you may notice light bleeding or spotting in the early stages, also referred to as implantation bleeding. Sometimes, bleeding can also be due to an infection, miscarriage, placental issues, or an ectopic pregnancy.
How Long Should You Wait To Take A Home Pregnancy Test?
Ideally, you should wait for one to two weeks from the time of ovulation to take a home pregnancy test (10). But you can get an accurate result if you wait until a week after your missed period. Home pregnancy tests detect hCG, which peaks during this period.
Right from the day you have sex during the ovulation period, your body is in the process of developing a new life inside you. While signs and symptoms before a missed period could indicate pregnancy, only a test can give you precise results.
If you are experiencing one or more of the early pregnancy symptoms, your pregnancy test result is negative, but you still think you could be pregnant, consult your doctor about it. Sometimes home pregnancy tests taken too early or late can also give a false negative. A doctor may suggest blood tests at a specific time for correct diagnosis.
