I Recently Had An Abortion, About 4 Months Ago Now...

I recently had an abortion, about 4 months ago now... I've always been a very skinny, in-shape person, but lately i seem to be gaining an extraordinary amount of weight, especially in my belly. It's AWFUL - I eat very healthy, I work out, but nothing seems to help. Is this normal? Am I going to be fat and frumpy forever?!
