21 Weeks Pregnant
At 21 weeks pregnant, you may be 10 to 15 pounds heavier than your pre-pregnancy weight. Your weight is about to start increasing rapidly. In fact, for many women, about half of their total pregnancy weight gain occurs during the next 10 weeks.
A common side effect of pregnancy is constipation. As your body releases progesterone, it causes the muscles to relax, including the involuntary muscles of the bowel. Therefore, the bowel takes longer to move things through and absorbs more water, causing your stools to be harder.
The risk of a urinary tract infection (UTI or bladder infection) also increases as the smooth muscles in the urinary tract relax.
Also, at about week 21 of pregnancy:
- Your ankles and feet may begin to swell
- You may get hemorrhoids -- many women do during mid to late pregnancy, due to the extra pressure of your uterus pushing on your rectum (see Hemorrhoids During Pregnancy)
- Your gums may become more sensitive.
Your uterus is now about half an inch above your belly button.
