Starting Clomid in 2 days!!!

My Dr prescribed me 50 mg Clomid for days 3-7. I started a full flow today so that means I can take Clomid in 2 more days!! So nervous. I've had 2 MC and 1 ectopic since my 2 healthy pregnancies 7 & 10 yrs ago. My most recent MC last month Oct 6th at almost 6 wks. This will be my first time taking fertility medication. I think I have low Progesterone. Hoping the Clomid and Metformin give me the healthy egg/eggs I need!! Any tips or words of encouragement are greatly appreciated!! Ty
