Hi all, I'm already very overweight so I'm conscious that I want to be as healthy as I can during this pregnancy. I'll be 5 weeks tomorrow, I should be OK to go for a gentle swim, right? I know a lot of online advice suggests exercising during pregnancy is perfectly safe but I'm just a little worried as I'm already going to be classed as high risk because of my weight so I don't want to do anything to risk baby.
