In the month of June, my period came normally. four days later my period returned in few for the same month; which is unusual for me. After which I fooled around with a boyfriend and there was genital contact without a condom and no ejaculation. I freaked out and got myself plan b pills just to be safe. I didnt feel any side effects. The next month I got my full period twice again a few days apart with severe cramping. I went to the doctor but felt uncomfortable discussing my sexual history. He mentioned that with periods like that their is concern of etopic pregnancy. After the second period for July, I am still experiencing cramping in my lower abdomen. I am concerned due to the risk of etopic pregnancy (fallopian tube pregnancy) after plan b. However, since mother nature sent it twice in June, I am wondering if it could be something else? Any advise?
