hello. I been having unprotected sex, and i haven t had my period for 5 months Ive always been really irregular, i don t have any pregnancy symptoms either. But last night i felt my lower abdomen a little bit upper my vagina hard, i thought it was just air, i had to pee, or it was cause i ate a lot in dinner. Today it felt the same though out the day and I also noticed small light bruises in the same area. please help me, what could this mean?
