1- what is the difference between braxton hicks and real contractions?
2- about a month after i have the baby im planning on starting at a gym to get back in shape,is it safe that soon? i know its kinda soon to think about that (im 21 weeks) but ive never been this big my entire life, im only 21 and am used to a size 3, im now about a size 10 and its torture i get out of breathe just showering

I know im this big and will be bigger for a reason, but I do want to do the gym thing and look great after i have my little boy
thanks for any advice
