Has this happened to anyone?

I have PCOS. We have been TTC for almost a year. During 2020, I only had three periods, two on my own and one after taking a course of Provera. The two I had on my own were after I saw my dr and took the Provera for 10 days.

The three periods I’ve had are almost always all brown blood. I know it’s “old blood” but can’t seem to figure out why it’s like this everyday while I’m on my period. Every once in a while there will be red but it’s mainly brown. I’ve asked my dr in the past because this has happened over the last few years and she just tells me it’s part of PCOS. Has this happened to anyone else?
