You should continue exercising. Physical activity will strengthen your body, preparing it for later months of pregnancy and childbirth. Exercise is not harmful to your baby, which is protected by your womb and the amniotic fluid surrounding the fetus. That said, avoid activities with a significant risk of injuries such as skiing or rock climbing. Make sure to continue meeting guidelines for aerobic exercise and strength training. Now is also a good time to do pelvic exercises to strengthen the pelvic floor muscles that support your abdominal organs. Pelvic exercises reduce your chances of experiencing complications during childbirth and help you recover faster.
