How many cycles of Femara?

Just wondering how many cycles you ladies did of Femara before finally getting pregnant?

I’ve done several rounds of Provera and Prometrium, followed by 4 rounds of Clomid, and I did a cycle this month of Femara for the first time. We’ve been TTC for 15 months with a miscarriage in April. I’m so tired of all these medications!!! I have been having cramps for a couple weeks and we BD on Christmas Day. So far, pregnancy tests have all been negative and I feel like my period may be coming.
