My boyfriend and I had unprotected sex last Thursday night. He started to pull out when he ejaculated but he didn't get all the way out in time. I went to my doctor and took Plan B Friday afternoon (14 hours after sex), however the more I look at the information the more worried I am. Technically Thursday night would have been prime ovulation time for me (it was 14 days exactly after the start of my last period). Are the odds really as bad as I think they are for this causing pregnancy or am I just scaring myself into an anxiety attack?

Normally I've very conscientious about taking my birth control pills (I've been on ortho-tricyclen since last June), but due to other events in my life, the doctor and I had taken me off them for two weeks. I started taking them again Sunday. Will that help, hurt, or have no effect on the situation whatsoever?

Please help. There are enough other things going wrong in my life that I certainly don't want to add pregnancy to the list.
