Depressed

Sierra
So I had my 21 day blood draw yesterday and it showed I did not ovulate. I am currently taking 50mg day 3-7, I'm so confused bc last month my progesterone level was a 46.5 and showed I did ovulate. I just don't understand how I could one month and not the next. Doc wants to up dosage to 100mg but I'm really concerned about the possibility of more two babies. Plus I think I'm ovulating now..don't know what to do. Any thoughts or suggestions
