Was it the Progesterone cream that finally gave me my bfp?

Almost 4 years ago we had a missed miscarriage. I figured it would only be a few months and we'd be pregnant again since everything I read said a woman is more fertile following a mc. No dice. I have read a small library of fertility books over the years since. Eastern and Western medicine. I started charting my cycles about a year ago. 2 months ago I started using Progesterone cream after ovulation because it seemed my luteal phase was too short. The progesterone literally changed my life. It made my normally horrible pms symptoms almost unnoticable and just generally improved my mood. So the 2nd cycle using Progesterone cream, I got my first triphasic chart and my first prenatal appointment is exactly 4 years and a day from the D+C I had for our missed miscarriage. I am holding my breath and praying it's viable🤞🏼 good luck to us all!
