So, a couple weeks ago I had my boyfriend over and we did some naked grinding. Yea, I know, dangerous. I know how dumb this is for asking, since I know how you get pregnant and how unethical this is, but is it possible to get pregnant from that? He didn't finish nor was there any prestuff. He started freaking out that I could get pregnant and I told him I wasn't. But, here I am, 4 days from my period and I don't have my normal pre-period cramps. I normally have them at least once a day for a week before it starts. I don't know if it's the stress from thinking that I could be pregnant that is causing them to not happen or what, but I just thought I would ask.
