think i may be pregnant. i am a little chubby. not fat or bad. lol. but my stomach is unusually tighter. i am moodier and my appetite has increased.. a lot. lol. im 19 (is it weird that i am that old and asking questions here..lol) and have been with my bf for three and a half years, but not ready. im in college and i just want to know if maybe my stomach tighting could be because im bloated from pms. its just unusual for me, so i was wondering. i wouldnt be far along either.

also my stomach is harder at the top. i was loosing weight, but i gained. rather fast. i have not got my period. i dont know the exact date either. i jsut want some knowledge. my stomach feels weird some times, but that is normal for me. idk. i know u can get pregnant even if u pull out, how likely is it tho. i dont really have any signs other than that. and an increase in sexual activity. (*shy*) lol. which i am not a very sexual active person.
