Have a rather confusing question (at least for me.) Had sex with my boyfriend april 12th at 2 am. and we realized when we were done that the condom had broke. There was a hole on the top. As I am not on birth control right now we went and bought the Plan B one step pill at CVS, exactly 8 hrs later. The thing is, my highest peak of ovulation was the 12th so I believe I was the most fertile yesterday. I read online that Plan B is not as effective when you are ovulating and that once the egg attaches it cant be prevented. An egg doesnt get fertilized until 4 -12 hours. I took the pill right in the middle of that time frame. I Have not had any symptoms from the pill and my period isnt due until the 27th. Am I at risk for pregnancy?
