  • The pressure exerted by the baby on the lower back also strains the muscles causing a backache.
  • The digestion process slows down as the digestive tract relaxes due to the progesterone hormone, leading to constipation.
  • The water retention in the body causes swelling up of the feet and ankle. In case of sudden swelling, go to the doctor as it could be a sign of preeclampsia.
  • It is common to experience leg cramps this week, especially at night. Cramps could also be due to calcium deficiency or dehydration during pregnancy.
  • To neutralize the acidity inside the mouth, excess saliva is secreted from the mouth.
  • Risk of Carpal Tunnel Syndrome due to an increase in the blood volume that puts extra pressure on the nerves, resulting in tingling feeling in the wrist and hands (13)
  • Pregnancy hormones can alter the tear production causing itchy eyes.
  • An increased buildup of fluid in the eyes can cause blurred vision.
  • As the uterus is growing, the muscles and ligaments in the pelvic area stretch, causing lower abdominal ache.
  • An increased vaginal discharge prevents uterine infections by restricting any bacteria from entering the vagina.
  • The hormonal fluctuations can lead to ‘pregnancy brain’ or forgetfulness during this period (14).
  • As the mucus membranes open up due to the hormonal fluctuations, there is more mucus flow through the nasal membranes that causes nasal congestion.

Your OB/GYN Visit

Here is what you can expect during your OB/GYN visit:

Physical tests

Other tests

Glucose tolerance test is done to determine maternal blood sugar. It involves a one step or two step approach (10).

  • One step (OGTT): Glucose levels are tested after a period of fasting, following which you will be given 75gm of glucose to drink. Your glucose levels are measured again one hour and two hours after the dose.
  • Two-step: This begins with the glucose challenge test, where you are given 50gm of glucose to drink, and the blood sugar level is checked after 1 hour. If the test result is abnormal, then a three-hour glucose tolerance test is done. The glucose levels are measured after fasting and at 1 hour, 2 hours, and 3 hours after the dose. An abnormal test result is an indication of gestational diabetes.

The doctor will advise changes in your diet and lifestyle, and may even prescribe medication, based on the test results. You should continue taking care of yourself at home.

Frequently Asked Questions

1. Are babies fully developed at 24 weeks?

2. How often would the baby kick at 24 weeks?

The baby might kick between the 24th and 28th weeks of gestation. But, there is no set number of times a baby kicks during pregnancy. Each baby follows a different pattern. You will eventually start to understand your baby’s pattern (11).

Around this week, a fetus starts to follow a sleeping pattern. Generally, a fetus sleeps in 20 to 40-minute cycles, sometimes extending to 90 minutes (11).

The 24th week of pregnancy means you are in the seventh month of pregnancy. Most of the baby’s organs are rapidly developing at this stage in pregnancy. As a result, you may be feeling a lot of movements of the baby. However, if you experience any contractions, you should consult your doctor. Nevertheless, these contractions are not always a cause for concern as they may also be Braxton Hicks contractions. Contact your healthcare provider if you notice any abnormal symptoms such as bleeding, unusual cramping, or reduced or abnormal fetal movement.
