So I got my period on the 3rd of November, I had sex with my boyfriend on the last day of my period which was the 8th. Unfortunately the condom broke but he didn't ejaculate inside me. Either way we went to cvs that same day and bought plan b. I took it within 30 minutes. I was also very sick so I couldn't tell if I got side effects or not from the pill. Anyways 5 days pass and I noticed some dark brownish/reddish spotting on the 13th. The next day it got a little heavier but not as bad as my regular period. Is this part of the side effects of plan b? How long will this bleeding last for?  and should my next period come early or late?
