Prescribed provera, (medroxyprogesterone) ttc, and had the withdrawal bleed. 9 days later spotted for an hour just light pink. Was that implant bleeding?

No. Most likely that was related to the lining of the uterus still being a little thin from the provera (medroxyprogesterone). Or it could be bleeding around the time of ovulation, if you ovulated. But not yet time for implantation.
