After speaking with my nurse yesterday, she was skeptical that I had a peak reading on cd 7. She asked me to come in for a blood test and my progesterone level came back at 8.73 which I think is fine for 4 dpo. However, I had started my progesterone cream yesterday. I forgot to ask how much one dose of the cream can affect progesterone levels. Does anyone have any idea??? Could my natural level have been below 1.4 which would mean I did not ovulate and the medication was bumping it up???
