Prometrium or Provera side effects

Has anyone taken progesterone supplements and had a ton of CM? I've been taking them the second half of this cycle to get AF back to normal after a m/c so that I can start TTC again next cycle. I've felt very tired and emotional on them, which I've read is to be expected, but I've had a lot of CM after not having much since going off the pill in November. Just wondering if this is normal.
