Pcos & TTC

So I obviously don’t have regular periods... I ovulated a few weeks ago. I started spotting on last Tuesday , this Tuesday has been a week and I’m still spotting/ having a light period but no cramps. Which is very unusual for me. TMI ... but when I wipe after using the bathroom I have clear discharge with a little bit of blood . It’s still so light I can wear just a panty liner. My bleeding or spotting has been pink or brown .... has anyone else experienced this & if so what was the cause ?
