Ive had unprotected sex twice this month a week apart. the last time of sex, 3 days later..My period came on early, it came on 6 days before expected date. the first day ive seen spotting, the second and third day I've had heavy bleeding. the 4th 5th and 6th day it went back to light/spotting. It stopped on the 6th day. my expected date for my period was the next day(7),the next day came and i showed no signs of bleeding.... So basically i has 2days of heavy bleeding and 4days of spotting. I'm not sure of what's going on, I never spot....HELP PLEASE!!
