someone please help me! I'm a 20 year old female who lost my virginity about 12 weeks ago (unprotected, I know I'm stupid). since then I've gotten pretty much on time periods they've just been shorter and I took a pregnancy test about a month ago and it was negative and I haven't been having any pregnancy symptoms at all but my belly seems to be different? I can't tell if it's just a little extra fat since I've always had a little fat belly but it's kind of at the bottom like a flap which isn't out of the ordinary for me it just seems a little more out there and I don't know if it's me convincing myself it is or what but my stomach isn't hard it's just like a flabby pooch at the bottom and I already had a negative test? I don't know if I've gained a little weight which I might have from overeating or what but I'd be about 12-13 weeks by now if I am pregnant. are there any tell tale signs?
