Clomid success? When did yours happen?

Hi y'all. Needing some serious support here. I have currently been TTC #1 for 20 months. I took clomid 50 cd 5-9. My doctor said "however odd you did ovulate but late" because CD 30 progesterone level was 34 (great improvement from My precious level of 1!) However I am now on CD 36 of my usual period length 37-39 and all BFNs. so heartbreaking !!! How many cycles did it take you to conceive with clomid ? i am so ready to throw in the towel and be done with it! Im so sick of being an emotional roller coaster!
