I had sex the first time . it hurt, like he was piercing through me . we used protection but i feel tightness below my belly. am i pregnant or what?

Get Tested: This is a personal subject and your decision. I advise all my adolescent patients that, if they have to ask, then they should get tested. I understand that may be easier said than done, but i strongly recommend you obtain a pregnancy test as well as an evaluation by a physician. This may be nothing, but you may have a urinary tract infection or other, more serious problem. See a doctor.
