Hello, I am 18 and have been having sex for three months. My period is often irregular. In December I had sex a couple of times unprotected with my boyfriend. I never got my period in January. I took two separate preg. test a week apart and both were negative, I am supposed to get my period next week, but lately i have been experiencing pain in my ovaries and under my ribs. This has gone on for about two weeks now. I feel bloated and nauseated. I am fatigued and have many head aches. I am scared I am pregnant, but my breasts are not sore and i have not had spotting. Could I be pregnant?
