... spotting last friday which turned into a heavy period that was on and off but is now back on and it's been 8 days. I am supposed to be starting my actual period according to my pack this upcoming week. I was not sexually active for 5 months prior to this starting last friday but when my period stopped for one day this week I did have sex but it was protected with a condom. It's been spotting for the last few days but it still hasn't gone away. Should I be concerned?
