Brown discharge during ovulation


I got a peak in clear blue advanced yesterday and I am supposed to ovulate today. I’ve also had a lot of ewcm the past 2-3 days and cramps on my right side. My husband and I had sex this morning and later this afternoon I had some brown discharge. Is it normal? I’ve never had spotting or brown discharge around ovulation.

PS: I have pcos but have been having quite regular cycles and always got peak opks. And, always got my period 14-15 days after peak. Got pregnant in April using OPKs but unfortunately ended in a chemical.
