Don't rush it and built back up gradually. Your body had just been through a heck of a lot over the past 10 months! I was swimming up until I delivered and of course, with my open cervix and all, couldn't go back in the pool till I got the go-ahead from my dr. at my 6-week appointment. Turns out I wasn't healed yet and told to take it easy (tough when you have a toddler too, but I digress). I just returned to the pool in the last couple of days and I'm 8 weeks pp. So far, my "swimming" involves a lot of floating around and sitting in the hot tub!! Lol!
