Struggling TTC - prescribed Progestrone??

Hi there!!

I’m 22 - My partner and I have been trying to conceive for the best part of 8 months, with absolutely no luck. I have had ultra sound scans and blood tests - the ultra sound came back that my ovaries are quite bulky, and do have cysts. However they are unsure whether I have PCOS or not. 

My doctor has now said that rather than trying to pursue the PCOS route(because it’s unclear) we need to work on exactly why I’m not getting pregnant - so she has prescribed me Provera(aka Medroxyprogesterone or just progesterone) to take for 5 days a month, for 3 months.

After the 5 days each month I should have a period, and she wants me to have a blood test on the 1st day of my period and then again on the 21st day of my cycle. Apparently this will show whether I am ovulating or not. If it comes back that I am not ovulating then I will be referred to a specialist for infertility.

I was just wondering if anyone here has experienced this process, and how you got on, what followed etc? And your experience with progesterone? Any tips?

Look forward to hearing from you! Thanks in advance
