I took plan B about 60 hours after having unprotected sex, however my boyfriend did pull out before he ejaculated but to be on the safe side I decided to take the pill. 5 days after taking the plan B pill I began to bleed very lightly sometimes bright red blood and other times brown. This has lasted just over a week and now it's 3 days off my due period date and I've started to bleed heavier, just like a regular period. Is this normal to be bleeding for so long, even lightly? This is the first time I've ever taken plan B. Thanks!
