Pregnancy Symptoms In The Seventh Week

Here are the symptoms that remind you about your pregnancy in this week:

  • Morning sickness will continue to be there for a few more weeks.
  • Weight loss because you might not want to eat much due to morning sickness; also vomiting will not allow you to gain much weight.
  • Acne due to the changes in hormonal levels.
  • Swollen and tender breasts due to hormones and increased blood flow to them.
  • Frequent urination as blood flow increases towards the pelvic area.
  • Fatigue and dizziness because your body is working extra; a drop in blood sugar level can also make you feel dizzy.
  • Excessive saliva due to morning sickness and heartburn.
  • Food cravings and food aversion.
  • Cramping, especially during the night time.
  • Spotting could happen after sexual intercourse or pelvic exam. However, bleeding during pregnancy accompanied by abdominal pain is not good.
  • Nasal congestion as the hormonal changes soften the nasal membranes. Also, the increased blood supply makes the mucus membranes swell causing extra secretion of the mucus.
  • Headaches triggered by morning sickness, fatigue, and emotional or physical stress.
  • Bleeding gums due to hormonal changes and increased blood volume.

It is not necessary for you to have all these symptoms. Some women might not have any signs, which is normal. Still, if you have any concerns, get in touch with your doctor.

Changes In Your Body During The 7th Week Of Pregnancy

You will undergo both physical and emotional changes. Here are a few you can expect in this week:

  • The breast size increases. The areola gets larger and darker and shows off some spots, which are the sweat glands.

  • Mood swings due to the hormonal fluctuations.
  • Strange dreams due to anticipation and fear of pregnancy.

The most prominent change in pregnancy is your swelling belly. Let’s see if it shows already.

How Does Seven Weeks Pregnant Belly Look Like?

How Does Seven Weeks Pregnant Belly Look Like

There is no visible change in the belly size during this week because the baby is still tiny.

However, in the second pregnancy, some women start showing the baby bump early because the abdominal muscles get stretched and weaker during the first pregnancy. Also, the uterus doesn’t shrink back to its original position.

If haven’t seen an OB/ GYN yet, you may do it this week but do some homework before making an appointment.

How To Prepare For The First Appointment?

This is what you can do:

  • Take all the medical records, including those related to the medications and supplements you are on. It will help the doctor to evaluate the risks of taking those medicines during pregnancy.
  • If you are pregnant for the second time and had any complications in your first, then share your concerns with the doctor.
  • Make a note of the LMP (last menstrual period) to help the doctor calculate your due date. If you forget or could not track your LMP due to irregular periods, then the doctor will go for an early scan to determine the age of your pregnancy.

So, what do you see in an ultrasound scan in this week?

Ultrasound Scan In The Seventh Week:

An early scan between the sixth and 14th weeks is called viability or dating scan (8). The reasons for an early scan include:

  • Rule out any chances of ectopic pregnancy
  • Confirm that the gestational sac is located properly inside the uterus
  • Check the pregnancy viability
  • Track the fetal heart rate
  • Assess the gestational age
  • See if the pregnancy is singleton or multiple
  • Check for spotting or bleeding associated with any pain

A seventh-week ultrasound helps you see the heart of your baby flickering, indicating the heartbeat. The presence of heartbeat reduces the chances of miscarriage to 5%.

The separation between the embryo and the yolk sac at this week can be clearly seen during the scan. The crown-rump length (from top of the head to bottom) of the baby is measured, which also helps in determining the gestational age.

An ultrasound can help detect two distinct heartbeats in case of twin pregnancy. The twin babies are of smaller size compared to the singleton babies.

Your OB/GYN visit will include a check-up for:

  • Weight
  • Blood pressure
  • Any health issues, if you have

Your doctor will explain the importance of nutritional and physical care. They may also advise you to change your lifestyle if you smoke or consume alcohol.

Nutrition And Wellness At 7 Weeks Pregnancy

A healthy diet and regular exercising are essential during pregnancy. Here are some wellness and nutritional tips you can follow during the seventh week.

Exercise:

Seek your doctor’s approval before you begin any exercise during pregnancy.

  1. A daily walk for 30 minutes or more is a moderate physical activity you can start with.
  1. Yoga is beneficial, but do it under expert supervision.

Nutrition:

  1. Increase iron intake: Due to the increased demand for blood supply, you can be at a risk of anemia (caused due to iron deficiency). Include iron-rich foods like green leafy vegetables, beef, and nuts in your diet.
  1. Prenatal supplements: Take them as prescribed by your doctor. They help you meet the recommended daily allowance of essential nutrients such as folic acid, iron, B complex vitamins and vital minerals.

Note: Prenatal supplements are not a substitute for a healthy diet.

Frequently Asked Questions:

1. What is toxoplasmosis and how can I avoid it?

Toxoplasmosis is an infection you might contract by eating undercooked or raw meat or by touching cat feces. Since the immunity during pregnancy is suppressed, you can get this infection easily. Therefore, eat well-cooked food and avoid cleaning your cat’s litter during pregnancy (9).

2. Does doing too many activities lead to a miscarriage?

No. Activities like exercises and sexual intercourse do not pose any risk of miscarriage provided they are done safely and carefully.

3. What are the risks involved during the seventh week?

Some pregnant women are susceptible to the below two risks:

i. Ectopic pregnancy:

An ectopic pregnancy (10) happens when the fertilized egg attaches itself outside the uterus. The place of implantation can be the fallopian tube, cervix, ovary or the cornua. The symptoms of an ectopic pregnancy are almost similar to those of a normal pregnancy at the beginning but become severe later.

You are at the risk of ectopic pregnancy if you:

  • had an ectopic pregnancy previously
  • have pelvic inflammatory disease
  • had surgery on your fallopian tubes
  • had IVF treatment

ii. Miscarriage:

During the seventh week, a miscarriage could happen due to any underlying health issues such as diabetes, hyperthyroidism, hypothyroidism or uterine problems, or an unhealthy lifestyle.

An early miscarriage can take place even before the woman knows about her pregnancy. Around 10-20% of women are susceptible to early miscarriages (11).
