I'm 38.5 weeks and have been swimming at least three times a week for the past two weeks since the local pool opened. I love it. I swim laps, very slowly, and then tan on the benches until I'm dry. It takes forever for the maternity suits to dry--all that extra fabric
. The DR said it was fine for me to swim. And I remember reading somewhere that it helps reduce swelling too. Something about the pressure of the water on the legs.
