I Am Devastated! 😪 How can this be?

I received my progesterone lab results from yesterday and I am devastated. It was 0.4!! I took one round of Clomid 50mg on CD 5-9. I still cannot believe my level was THAT low! Does that mean my level was always at 0 before Clomid. I cannot imagine my level being that low ON Clomid. I cannot stop crying! 😪 I felt like my body was ovulating. I had abdominal pain and still have sore boobs as I’m writing this. My doctor wants me to try another round at 100mg CD 5-9. Any ladies have gone through this? Encouragement, pointers, stories like mine that ended up with a BFP right now is greatly appreciated. Thanks!
