My boyfriend and I grinded (dry sex) with our underwears on. His boxer was wet, and my underwear had a hole by the vaginal opening (I didn't know until much later), but there was no skin to skin contact. I felt sick right after we were done, and I became paranoid. I took Postinor 1 about 14 hours after the dry hump just in case, and 5 days after I took the pill, I spotted. My breasts became tender (they hurt when I touch them) but I have no cramps whatsoever. I do feel nausea every now and then. I'm stressed because it's my exam week, and the paranoia about me possibly being pregnant. I know that I'm not pregnant because no penetration happened, but I can't stop worrying about me becoming pregnant. Could I be pregnant? or am I just being paranoid?
