First of all, I would like to note that I have had my period since 7th grade, when I was 12. I have never had a regular cycle. In 2012, I had my last period in May, and didn't get it again until September, and then December. My most recent is this year, March 12-18th. I then had intercourse on the 29th. There was a condom on at first, but by the time I found out that he took it off, it was too late. He pulled out, but I do not trust that method!!! I was livid. So, today, Apr.
