So my period cycle is very different, I’ll have a period one month and the next I won’t till the following month. December I didn’t get my period since I did the month before, December 29 my boyfriend and me were messing around. We haven’t had actual sex but I do grind my butt against his penis. This has only happened twice. I was supposed to get my period today and the week before I had spotting and discharge. Is there a possibility I could be pregnant?
