I've been feeling real sluggish here lately my stomach stays sort of upset, I have intense hot flashes, I get dizzy and I pee a ton. I have gained about 15 pounds but here's the catch I haven't had sex at all since July so if I were pregnant I'd be like 8 months and I hardly have a belly much less a 8 month pregnant belly I'm 145 pounds normally so it would be completely obvious if I was pregnant especially 8 months along. So what could it be if in not pregnant??
