Perimenopause and progesterone

I am in perimenopause, and had the worst hot flashes (12 a day) where I was profusely sweating. My Dr prescribed progesterone only pills—200 mg, continuous. I can’t be on estrogen due to blood clotting in the past. At first, I loved it, I slept better and the hot flashes were gone. Then I started getting painful breasts and shorter periods. I went down to 100 mg for the last two weeks. The painful breasts went away but I’m having a period that won’t stop… it went straight into spotting and then into another full blown period (16 day cycle) and also the worst cramps I’ve ever had. It’s been 4 months ( but only 2 weeks that I went down to 100mg). I’m thinking of quitting it all together. I’m not sure what’s worse—hot flashes or severe cramping and non stop bleeding. Does this get better? Has anyone else experienced this??
