I was on birth control pills for about 5 years. I have been off of the pill for about 3 months now. My partner and I had unprotected sex and he told me that he didn't pull out in time. My last period lasted for 4 days and on the fifth day there was nothing, so I started wearing regular panties with no liner. On the 6th day I noticed brown spotting in my underwear. Can anybody please tell me what this could possibly be?
Base on what I am experiencing, that is nothing to worry about. I am menstruating every month with the same situation and every end of my period, I would notice a brown spot on my underwear. That is regularly happening to me.
