My average period cycle varies between 26 to 27 days. I am 26 years old. In December I had multiple physical encounters with my fiance leading me to take i pill 3 times in the same month. Although I got my period on the 2nd January on time, my flow is bare minimum than usual. Also we got intimate on the first day of the period and it was unprotected! I am concerned whether am I pregnant and if not then why is my flow unusual? Is it something I should be concerned about? Please Help!
