Hi I was recently 8 days late for my period,however it arrived on the 8th late day,it was lighter than usual and not as long,on the 4th day it ceased so my husband and I had sex,next morning it returned for the day,very light,then 9 days later I had a lot of brown discharge that lead to somewhat of a period over 3 days,so I essentially got 2 periods in 16 days?
