I had unprotected sex two weeks ago on Friday, I got my period right the next Morning on Saturday, and it was completely normal. I wasn't sure if I could be pregnant, so I took the morning after pill; the problem was that I took it a week later on the Sunday that just passed. Yesterday, Friday, I just got my period again but this time I didn't get any cramps or anything. I'm 14 days into my cycle. My last period lasted 7 days, which to me is normal. Albeit, I have never had my period just a week after the last. What could this mean? What caused this? I'd appreciate your help, thank you.
