What are the symptoms at week 20 of pregnancy?

Making it to the 20 weeks pregnant might feel good. However, some women experience some set of annoying pregnancy symptoms.

Vaginal discharge

Many women experience vaginal discharge and are expected to increase until delivery. But if your discharge is yellow or pink and foul-smelling, it can be a sign of bacterial infection and should be informed to your healthcare provider. 

Indigestion and heartburn 

As the baby starts to crowd the digestive system, the symptoms relax the stomach muscles. As the muscles in the stomach relax, the acid may travel up to the esophagus and the acid may cause heartburn.

Leg cramps

For some women, the increase in overall body weight stresses out the leg muscles. Also, the blood circulation decrease and that stasis and pooling of blood in the leg might put pressure on the nerves or the blood vessels, which can cause leg cramps.


As your uterus expands, nerves are pressed making some women experience swelling on the legs and arms because of the excess fluid retention in the body, accumulating in the hands and legs.

Breast changes

Hormonal fluctuation brings a change in the structure of the breast. Initially, with the rise in the pregnancy hormones, the breasts increase in size and are more sensitive

During the second trimester, the tenderness of the breasts reduces, but the milk glands in the breasts develop, and fat deposits increase. Small bumps are also formed around the nipples. It produces oil that stops the breasts from getting dry.

Self-care tips

Weight gain, swelling, and added pressure over the nerves are some of the significant changes that happen during the second trimester. The added pressure over the nerves can cause swelling and cramps. 

  • Drink plenty of water and stay hydrated
  • Avoid standing for a long time and continuously change the position in which you sleep.
  • Keep your legs elevated during sleep to relieve the pressure in the legs.
  • Take warm baths to soothe your nerves and reduce the pressure over it.
  • Stretching helps a lot with the pelvic pain and at the time of delivery it helps with short labor and lesser complications
  • Stretching your feet upwards helps to reduce leg cramps. The cramps and the swelling are a part of pregnancy and are completely unavoidable.
  • Choose healthy and short meals throughout the day rather than a few heavy meals.
