I got my last period July 23rd, and it lasted until July 27th. A few days later, on the night of July 29th-July 30th, I was having sex and the condom broke. He hadn't come yet so we stopped, but I took the morning after pill (generic, not Plan B) as a safety measure about 12 hours after we had sex. I had what was essentially a period about a week later, on August 3rd, and I think it lasted for about four days or so, and was very similar to my regular periods in flow and length. It's now August 26th and I've yet to have my period, so should I be counting my cycle from the Emergency Contraceptive period or my last period in late July? Should I take a pregnancy test, and what are the chances that I am pregnant? Please answer, I'm in a state of paranoia.
