I tried a progesterone only pill for while. I ended up having bleeds every other week - it was like my menstrual cycle was just 2 weeks long.

I went back on the regular pill and it took a year before my uterus fully settled down. Technically, being on the pill is risky for me (age, weight and a family history of DVTs) but this point I'm afraid to try anything new in case it plays havoc with my cycle again.
