has been a consistent 21 days, with severe cramping and heavy bleeding. Last January I went 6 weeks between periods
, and thought I was pregnant, but was not. Since then there are anywhere from 10 days to 21 days between periods, still very painful and heavy. I have had a couple cysts in the past, but none currently. I have been tested for PCOS and bloodwork to check my thyroid, but everything has come back OK.
