Pregnancy Symptoms In The Seventh Week

Here are some 7-week pregnancy symptoms you should look out for.

  • Morning sickness will continue to be there for a few more weeks.

Christine Keys, a mother of three, shares about nausea during the seventh week of her third pregnancy. She says, “My nausea is okay, but as soon as I start walking around and I start moving, it (nausea) just gets much worse, and I can’t do stuff. It just comes and goes throughout the day. So, I just stay in bed and rest. She adds, “Something that I think is helping is protein shakes in the morning and a couple of crackers. That seems to help my stomach for the rest of the day (i).”

  • 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 and darkening of skin due to the changes in hormonal levels.
  • Swollen and tender breasts due to pregnancy hormones and increased blood flow.
  • Pregnancy 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.
  • Pregnancy cravings or food aversions.
  • Cramping, especially during the night time.
  • Spotting (if you experience it, consult your obstetrician).
  • 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.

But sometimes, you may also have some weird symptoms. Malinda Rocha, a mother of two, experienced an abnormal symptom during the seventh week of her second pregnancy. She shares, “I’m getting a lot of pimples around my hairline. I was getting pimples on my chest and my back, and I had that with Felicia (her first child) also. But, this time, right beyond where my hair is, I have so many pimples, and my hairline is inflamed (ii).”

protip_icon Point to consider
Due to the intestinal muscles relaxing during this stage of pregnancy, some women may also have constipation. Constipation can be relieved by consuming a diet high in fiber and probiotic foods, such as probiotic yogurts (2).

Twin pregnancy at seventh week

In a twin pregnancy, the symptoms are same as that of singleton pregnancy but the intensity might be more. The vomiting sensation is heightened and abdominal distension will be more. Also, the pregnancy symptoms will start earlier than in a singleton pregnancy.

Changes In Your Body During The Seventh 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.
  • You will begin to have the pregnancy glow. The estrogen hormone can bring about brightness to your face, make your hair thicker, and skin softer.

  • Blue veins are visible near the breasts and the pelvic area due to the increased blood flow in these regions.
  • 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.

What Does A Seven-Week Pregnant Belly Look Like?

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

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 you 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 this week?

Ultrasound Scan In The Seventh Week

An early scan between the sixth and tenth weeks is called viability or dating scan. The reasons for an early scan include:

  • Rule out any chances of ectopic pregnancyto confirm that the gestational saciXThe first structure to form in pregnancy, containing amniotic fluid and surrounding the fetus is appropriately located inside the uterus.
  • Confirm the number of sacs to know if it is a singleton or multiple pregnancy
  • Check the pregnancy viability by tracking the fetal heartbeat
  • Track the fetal heart rate
  • Assess the gestational age
  • Check the viability of the fetus if the complaint is 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 this week can be clearly seen during the scan.

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

  • Weight, height
  • Blood pressure
  • Blood investigations
  • 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.

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 (7) .

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 and no added previous risks are present.

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 happens when the fertilized egg attaches itself outside the uterus (8). 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, hyperthyroidismiXOverproduction of thyroid hormone by the thyroid gland , hypothyroidismiX A condition when the thyroid glands produce does not produce enough thyroid hormones or uterine problems, an unhealthy lifestyle or blighted ovumiXWhen the fertilized egg doesn't grow into the embryo after implantation and causes a miscarriage in the first trimester .

An early miscarriage can take place even before the woman knows about her pregnancy. Around 10-20% of women are susceptible to early miscarriages (9).

4. How can I manage my stress levels during the 7th week of pregnancy?

Delegating tasks, practicing prenatal yoga or meditation for relaxation, and enrolling in childbirth education courses are ways to reduce stress. Taking a break from work to relax and seeking support from social workers to alleviate financial or other stressors may also help (10). Prenatal massage can also be helpful, but it should be avoided during the first trimester (11).

5. What is the average pregnancy weight gain during the 7th week?

Pregnant women usually put on 25 to 35 pounds. In the first three months, they gain about 2 to 4 pounds (1 to 2 kilograms). From then on, gaining 1 pound per week until delivery is considered normal. Nevertheless, the amount of weight gain varies among women (12).

The 7th-week pregnancy is when the embryo is about a blueberry size and attains a human-like structure. Mothers begin to experience pregnancy symptoms such as nausea and vomiting from the 7th week of gestation. It is the phase when you start to experience body changes such as pregnancy glow and increased breast size. The symptoms can be similar for twin and multiple pregnancies. There won’t be any visible increase in belly size at this time. Despite your pregnancy being in the early stages, remember to take good care of your health and eat well.
