I am 18 years old and I am on Ortho Tri-Cyclen Lo. I take the pill everyday at the same time everyday. My boyfriend and I always use a condom and he pulls out- except one time. We had unprotected sex for about a minute and he claims he did not have any pre-*** and I am still taking the pill everyday on time, however two days after we had sex I started to cramp and have been dizzy for three days straight. We had intercourse 12 days after the start of my period and although I am not supposed to ovulate that is what the cramps felt like and I have never experienced this dizziness before...I am almost sure I can't be pregnant because I am on the pill and it was only for a minute but can someone please reassure me on if this is correct??!!
