My boyfriend and I had unprotected sex Sunday the 28th. My last period had started on the 19th, and at my normal OB/GYN appointment my doctor on the 29th had recommended that I take Plan B "just in case." Five days after taking the pill I started bleeding (Sept 3rd).
Of course this surprised and scared me, as it was only 15 days after my last period. The flow is lighter than a normal period but is still dark and thick like a menstrual flow. I was thinking that the Plan B had simply caused me to cycle earlier than normal.
Then last night (Sept 3rd) by boyfriend and I had unprotected sex again. He did not ejaculate inside of me but I know that there is some risk of pregnancy from pre-cum. What is my risk at this time, with the bleeding and all? Do I need to invest in another Plan B or is it possible that I'm safe?
