Hi. I am a 16 year old girl and over the past month, I have been having lower abdominal pain when I climax during masturbation and now the pain has become kind of constant. My period was also supposed to come about a week ago but still hasn t come. I am unsure of what the problem is because my boyfriend and I haven t had sex in about a month and a half. And I had my period since then. But I really want to know what s wrong. Am I be pregnant or could it be something else? Please answer as soon as possible.
