Can chlorine in the swimming pool hurt my baby?
No. Many natural barriers in your body, including the cervix and amniotic sac, protect your baby from external substances such as chlorine in a pool or even soapy bath water. In fact, swimming is one of the most beneficial and comfortable forms of exercise you can do during pregnancy, as the water imparts a weightlessness that many women find soothing. That said, I recommend that you check with your doctor before beginning (or continuing) any exercise program. Also be forewarned that if there is any concern about vaginal bleeding, the potential rupture of membranes or other signs of preterm labor, swimming--and all other forms of exercise--should be discontinued immediately.
