TMI Red Discharge‼️⁉️⚠️🤷🏾‍♀️

Last night I had this discharge! Sorry for all that's in the pic. I have PCOS. I have regular periods. First time I've seen this. I did have sex on ovulation dates Dec. 16-22. I'm 8dpo. My AF will be here Jan.4. Its a little early to be bleeding. Im used to my sore boobs but this time it's killing me to even wear a bra. Cramping and twinges for 4 days straight but I don't have cramping until the beginning of my AF. The blood is gone now. Want be able to see my doc until Tuesday. Just needing some feed back if anyone has had this type of discharge.
