Hi, I'm currently on my period and I'm experiencing an unusual light bleeding. I would normally have a 6 day period with lots of cramps and bleeding, but this is the 3rd day and it seems as if its about to leave. The first day I had a pink tinged discharge and then a very light spotting type day. Only used one pad the first day. The second day it was a little heavier and I used two pads. Now today it's back light and it's only there really when I wipe. I had unprotected sex with my fiancé a few days before ovulation. What could this be?
