Just wondering what the risks are if I don't return to pre-pregnancy weight before getting pregnant again. I gained a lot during first pregnancy and have so far lost about 3/5 of it and am doing slimming world, but am not using birth control. Should I use protection until I am at a healthier weight? Currently my BMI puts me in the overweight category which I wasn't before. This is the only reason I am thinking of going back on the pill to be honest.
