Hi, i just finished my first pack of bcps and i have missed my period. Im 7 days late and i have had cramps like i was going to start my period for about 2-3 weeks now. i had very sore breasts, just on the sides toward my armpit. As of right now the breast soreness has almost gone. When it came time to get my period i had only a bit of brown discharge, sometimes a bit of pink when i used the restroom. I didnt even need to use a pad..... weird for me because i usually have a 5-6 day long period that is very heavy. I had unprotected sex all throughout the month. What could be wrong?
