Fetal position and movements: There is sufficient space inside the uterus for the fetus to move freely. You can feel the movement and kicks that feel like wiggles and flutters, also referred to as quickening. The fetus starts to suck its thumb, something that you can notice during an ultrasound. Also, the baby develops a regular wake-up and sleep pattern by this week.
What Symptoms Of Pregnancy Do You Experience In The 20th Week?
Pregnancy symptoms that you may experience during this week include:
- Weight gain: The weight needs to be as per the BMI (9):
|BMI||Below 18.5||18.5 – 24.9||25 – 29.9||30 and Above|
|Weight gain (Pounds)||9-15||8-14||5-11||3-8|
- You may develop food cravings, a liking or disliking towards certain foods, due to hormonal fluctuations.
- Vaginal discharge, which prevents any bacteria from entering into the uterus through the vagina. Make sure to speak with your doctor in case the discharge has a foul odor.
- You could experience leg cramps at night, due to a deficiency of magnesium or calcium.
- The progesterone hormone relaxes the digestive tract, leading to slowed digestion.
- The stomach is pushed upwards by the growing uterus, making the gastric acids to enter the esophagus to cause heartburn.
- Water retention in the body causes swelling of the hands and feet. Sudden or excessive swelling could be an indication of preeclampsia.
- The relaxation of the mucous membranes causes constriction in the nasal membranes that lead to nasal congestion and shortness of breath.
- Pressure on the pelvic and rectal nerves due to the growing uterus causes swelling, or hemorrhoids.
- The excess blood flow towards the lower part of the body causes pooling of blood in the leg nerves, resulting in a varicose vein.
- Increased blood flow to the lower part of the body sometimes deprives the brain of sufficient blood supply, causing dizziness.
- The slowed digestion causes the food to stay longer in the digestive tract causing constipation.
- Braxton Hicks contractions are irregular and painless contractions that prepare the body for labor.
- The leg cramps, increased frequency of urination, and the body aches may disrupt you sleep at night.
- The hormonal fluctuations can cause headaches during the week.
- With an increased blood flow in the body, you may experience hot flashes.
- You may develop the restless leg syndrome, a tingling sensation in the leg and an urge to move the legs in an uncontrolled manner. It could be caused due to low hemoglobin (<11 g/dl) level, RLS in the previous pregnancy, history of RLS before conception, or low folate (10).
Along with these symptoms, you will experience certain physical and psychological symptoms as well.
