Ladies! This is exactly what I chose to do. I rode outside until I was 5.5 months pregnant. And since then I've been using a trainer inside and it is only because my husband is concerned about my safety. I decided not to stress him out. But I still play tennis at 37 weeks! And who said that I cannot fall on the court. My doctor and my body tell me that I am fine and I should go for it. So why not?! And if my labor starts after a tennis lesson or a spinning session at home, then so be it! I am looking forward to it.
Thanks to all of you!
