Hi, I know this is an old thread but i am searching for information on competitive sport during pregnancy and after birth. i can gather from the previous posts i shouldnt stop what i am doing but i am concerned that my heart rate has been around 145ish whilst at the gym. what about after birth? I also play Baseball and i wondered how long after birth do i have to wait to play again? I have searched the forums and this is the closest i have found to my situation.
