I'm having light pink stringy discharge. My period ended on Oct.1 on the 4th I had light bleeding. This has happened many times over the past few weeks. I thought my period came on the 18th it was a brighter red but it lasted a few hours and was not much at all. Again only when I wiped I saw this going on. It's light very light pink with stringy discharge like ovulation. I'm very sexually active, unprotected. I've had sex everyday this month. Help? Is this a weird cycle? I have pcos, is that it?
