Weight and miscarriage

I just wanted to complain about one of the unfair side effects of pregnancy that doesn't result in a baby: weight gain! I gained about 8lbs during my first trimester. Not too much, though I'm only 5'2" so it's something. I've never had any issue losing weight, but post d&c these damn pounds just won't come off! I'm not trying too hard; since I want to ovulate I don't want to exercise too much. I've had trouble with regular ovulation in the past.
