confused

Last cycle I was 7 days late and then bleed for 4-5 days. ( regular is 4) I had extreme back pain, passed massive clots. Had a faint line so I chalked it up to chemical pregnancy! ( first ever conception! Yay) went on regular life and thought that was af just late. Now, today cd 16 I had a fleshy spot this am, put on a pad after work cause I had stains in my undies like a period. Walked the block with my dog and the pad had some on it. Again, like. Period but not as much. I'm letting it play out but I'm wondering is this ovulation bleeding? Or is this my period regulating and I really did have a chemical? Hmmmmm Today starts fertile week but I think I ovulated two days ago? ( cramps & almost + opk)  anywhoo.... that's my current situation 🙆🤔👼🏻
