A week ago I had sex and the condom broke (it was the 19th day of my cycle which varies between 32-40 days) and I'm not sure how much went inside me but I know not all of it did as he pulled out. The next day I took Plan B (18 hours after sex). I have taken it 1 other time about 5 months ago and 5 days later I experienced bleeding. This time that did not happen. Is this normal? and What are my chances of becoming pregnant?
