Help! Taking Progesterone and keep having my period early!

Jordan • TTC #1. PCOS and Irregular

My OBGY put me on Prometrium 100 mg daily because my Progesterone levels were low. But last cycle my cycle was 13 days so she up’d my dose to 200 mg daily. Currently CD13 and spotting with period cramps. I’m SOO frustrated and I think I’m just going to stop taking the Progesterone. Thought? Suggestion? Anyone with similar experience?

I haven’t even had a chance to ovulate in the past month since my period comes every 2 weeks now.
