I was given 21+7 bcp by a "doctor" last year. I was really on the edge about taking them. I took them for 4/5 days in August then stopped and got a huge withdraw bleed. took again another 4 in early sep and stopped. bled. took again until end of sep then stopped for good (got a big bleed).

when my periods came back after being jumpstarted with a progesterone shot, they've been showing up every month roughly every 24-28 days but like barely ANY flow. they've been that way now for 9 months. ultrasound confirmed endo lining of 4 mm midcycle. could this be from using those pills for such a short time?
