Hi, I had sex 4 days before my period with protection but after my boyfriend ejaculated we found out that his condom had broken so he ejaculated in me. I took the emergency pill/morning after pill about 2-3 hours after this had happened. I am currently not on birth control and my menstrual cycle is regular (28-30 days). Now I am one day late for my period. What are the chances that I might be pregnant?
