My boyfriend and I are usually very careful, we are both virgins and plan to stay that way until our marriage.
One night we both got a little carried away, and we had "dry sex" (I guess that's what we're calling it these days) where he basically just humped me dry.
Well, problem is, I was naked, he was wearing basketball shorts that either had pre-ejaculate or my feminine secretions on it, or both... I still don't know.
My periods are usually irregular, but I've kept a calendar of them for the past few months. I am 10 days late according to the calendar. I am VERY worried..
No pregnancy tests yet, my breasts are swollen and I've been cramping for a few days.
Any advice would be appreciated!

Sperm cannot go through "basketball shorts" and still live to travel up the vagina. You are safe.

Started my period this morning(:
Thank you!

But to be honest, if you are completely naked and he just has shorts on, someone is going to lose self control at some point soon and entry will be done, without condoms or birth control pills being used.

Yeah I know, we both decided we're not doing anything like that again so we don't end up having sex.
Thank you for reinforcing that! (:
