I had sex on Feb 13th. My period was due on Feb 27th. On the 26th I started what seemed like a normal period. Now it is March 28th and I was to start again on the 25th and have yet to start. I am normally always start between day 26-29. Could I be pregnant?

Everyone has off months. You are only A couple days late. If it doesn't come in the next several days, take a test.
