I was just wondering, im new to birth control, was on it a full month and had unprotected sex, I got nervous and took Plan B on sugar pills while on period that month. I started new pack like normal on time and now a full week before my next period I have been having brown discharge mixed with clear discharge like im ovulation but you aren't supposed to ovulate on the pill. Im due to start my normal period in 4 days on sugar pills... did Plan B mess up my cycle or could I be pregnant?
