Tried to wait it out

This is my first cycle of clomid and progesterone oral pill. Ovulation happened on 7/22. Period was expected on 8/5 at 14 dpo which is usual for me.

At 12 dpo I had light pink spotting which looked like implantation bleeding ( I have experienced it previously).

At 13 dpo i had fairly good amount of brown/dark reddish spotting but nothing I could catch on a pad.

Since 14 dpo I have only had clear or off white color cm and loads of it.

I stopped taking progesterone on 13dpo. Basal temp dropped 0.5 degree since stopping progesterone.

Negative pregnancy tests on dpo 13,14,15.

Does anyone know what could be happening? Did I already have my periods or should I be expecting it? Can I still be pregnant?
