Help! I was raped when I was 12 years got an std and didn't know what it is or tell any1 about it 5 years later I have it treated, I thought if you have had an std for that long ots impossible for you to get pregnant therefore I had no problem with having unprotected sex with my partner, I missed my periods november last year for the whole month, the following month december I got them, january has ended and yet again I haven't had my periods, november I took 3 home pregnancy tests which tested negative. My nipples hurt, I'm moody, I have cravings, nuesea, my stomach feels weird, I'm tired and sleepy all the time, I frequently need to urinate. Could I be pregnant?
