Two weeks after my abortion I had unprotected sex with my partner. He pulled out before he ejaculated inside of me but now I'm worried . Because the same odor from my vagina while pregnant is back. And the same pain while I was pregnant from my stomach also is back. Mind you I'm only 18. I never went back for a check up because of money reasons. So I never got the chance to take birth control or get the shot. Is it possible I'm pregnant again?
