Falling Progesterone

Tanya

I had bloodwork done the day after my bfp. I went back in today for a 1 week recheck. My HCG was great (over 4000 at 5 weeks), but my progesterone wai falling instead of rising. They put me on progesterone suppositories until I'm 10 weeks. I have PCOS and it took 3 IUIs with Femara to conceive. Could this be related to PCOS? Has anyone ever dealt with this?
