Genetic.. i guess :(

The one reason I've always been deathly afraid of getting pregnant is WEIGHT GAIN. I am by no means small, as all of the women in my family are big. I'm 20 and I've been able to keep my weight down.. but now I'm pregnant. And I'm gaining. Fast. I walk every day, but my diet has gone piss poor since moving in with relatives..

All of the ladies in my family have never been small, but they blew up after just their first pregnancy. Keeping my weight under control hasn't been too hard until now. I don't have any ED's or anything like that.. guess I'm just venting. It's the one thing I promised myself since I was little, that I would be conscious of my weight and work a little harder than they have to accomplish it. I want to get up and exercise more but this pain in my hip is ridiculously bad and I live in a big country county with lots of land and lots of highways, with no means of any real transportation atm, so even walking is hazardous.. I'm just disappointed in myself.. I weighed about 155-160 at the beginning of my pregnancy and at a crisp 21wks the scale at my OB's said 1 7 8 !!!
