I have always loved and occasionally played tennis. I am 7 weeks pregnant, and my sister invited me to join a tennis team to play doubles with her. Its less running because it is doubles, but I'm wondering if it would be safe. I had a miscarriage before, not from over-activity, or any reason really, but now I must admit I'm a little paranoid. I have a duaghter who is 3, and my pregnancy with her was healthy, and I played tennis for fun once in a while during, do u guys think it would be ok this time around? :)
