Is it safe to play tennis during pregnancy? You are probably one of those who love to play tennis. Well if you are a very good tennis player, playing tennis during pregnancy is probably safe. However, playing tennis can likely make you fall and often involve rapid changes in direction. And these rapid twists and turns could make you more prone to falling, which is dangerous to your pregnancy. You could begin having contractions if you fall or you could start bleeding if the placenta detaches from the uterus. Thus, playing tennis is not advisable because it can place the fetus at risk of premature delivery.
