Hello, I have been doing a great deal of research recently, as a couple days ago my boyfriend and I had been fooling around, and after he had touched some precum that had leaked out of his boxers, he proceeded in fingering me shortly after. We have been worried since, as I had already been late for my period a couple days before that happened, and I still have not gotten it yet. I had thought that it was probably due to the stress of school and whatnot, and I dont usually have too many premenstrual symptoms, but I started getting cramps in my lower abdomen and tender breasts. Should I be worried? Thanks so much.
