I'm 37 weeks with twins and haven't really had any swelling until today and I only have it in my right thigh, I measured and it's 2 1/2 inches bigger then the left thigh. I called my doctor and she said its normal for one leg to swell more then the other. But I just don't feel right about what she said. I've done research and am worried it could be a blood clot, do you think I should go in and get it checked out, or do you think it's normal?
