Early Menstrual Cycle
I started my period on December 24. I then had unprotected sex on January 1st and took the morning after pill saturday january 2nd. It is now only 16 days into my cycle and I got my period! What does this mean? Is it due to the morning after pill??
This may be a result of the emergency contraception that you used. It can cause irregular bleeding. You should perform a pregnancy test to make sure that you are not pregnant and repeat this test in two weeks.
