My boyfriend and I had a condom break so the next morning we got the plan b pill. I had an appointment the next week to get on the pill and just got chateal. I haven't started it yet because I was hoping to start my period but it is nine days late now and I took a pregnancy test which was negative. I have been stressing out about a lot of things as well and am wondering if I should even expect a period this month? Should I just go ahead and start the chateal this Sunday?
