Normal or abnormal? TMI. TMI.

Tmi.

Sorry for tmi. I have been Ttc for 10 mo. I have only just been getting “regular” periods recently, cycle is generally 33 days. This month on CD 29 I started “spotting” only when wiping.

On CD 32 I had small amount of bright red blood when wiping again. With 1 “larger” blood clot. Previous day I had sex. But I’m assuming this is AF now even though it’s dark brown/black discharge.. I didn’t have any cramping with earlier discharge and now I have more painful cramps. I’ve been having this discharge for 5 days now. Spotting started 6 days earlier than AF was expected. Should I see a doctor asap or could this just be AF (normal?) any advice would be nice as I’m confused what is going on 🤷‍♀️
