I've had sex throughout ~ 1st trimester was fantastic but it's gradually getting less and less appealing to me I feel awful about how I look now and find it hard to umm participate fully I guess LOL as my back is always aching and stuff. But my pregnancy has been 100% healthy and normal.. minus a bit more weight gain than I would have liked, which I don't think has anything to do with sex, in fact, maybe I should have MORE sex to get my physical activity in..
