Progesterone anyone?

So I had a Mc in July due to an abnormality and another one in September. We recently did a bunch of blood work to make sure there was nothing me or my fiancé were passing on. And everything came back CLEAN! So she put me on progesterone and I have to take it twice a day. I’m jw if anyone else has done this? I carried my first 11 weeks and my second 5. And during my second one we tested my levels every two days but I never made it to my first apt. Any info or advice would be appreciated
