What Symptoms Do You Experience In The 13th Week Of Pregnancy?
By this week, the morning sickness subsides, and you start feeling energetic. However, if you are carrying twins or multiple babies, then the morning sickness may persist. Here are some other symptoms you will experience during the 13th week of pregnancy:
- Increased energy level, as the morning sickness comes to an end by the beginning of the second trimester.
- Food cravings/aversions due to hormonal fluctuations. You may even crave for certain foods and dislike others.
- Indigestion/constipation as the progesterone hormone relaxes the digestive tract and slackens the digestion process.
- Dizziness, due to reduced blood pressure, as more blood is pumped to the fetus.
- The hormonal changes increase the vaginal discharge or mucus that prevents bacteria from traveling to the uterus.
- The progesterone hormone relaxes the digestive tract that slows down the digestion process causing gas and bloating.
- The urge to urinate more frequently increases due to hormonal changes.
- Reduced sense of smell and aversion to certain smells due to a change in the hormonal levels.
Along with these, you will also notice physical and emotional changes.

Your OB/GYN Visit
These are the following things you can expect during your OB visit:
- Blood pressure
- Weight check
- Combined screening test evaluates the risk of chromosomal abnormalities in the baby. It includes an ultrasound scan along with a blood test (11).
- Ultrasound for nuchal translucency is done to evaluate the thickness of the fluid behind the baby’s neck. The thicker the fluid, the greater is the risk of Down syndrome in the baby.
- Gestational age and nasal bone determination to visualize the nasal bone and determine the fetal gestational age. The nasal bone may not be properly visible in babies with Down syndrome.
- A blood test measures the level of proteins in the blood sample.
- PAPP-A, a placental protein produced during early pregnancy with an unsatisfactory result indicates the risk of chromosomal abnormalities.
- An abnormality in the level of this placental protein human chorionic gonadotropin indicates the risk of chromosomal abnormality.
The risk of Trisomy 18 and Down syndrome can be assessed from the combined results of these tests. In the case of abnormal test results, the doctor recommends additional testing like ultrasounds, amniocentesis, cell-free fetal DNA, or chorionic villus sampling.
