IVF Mommas - when did you stop progesterone

So I got my 3rd beta back today. HCG 6521 prog 37 and E2 850. All great numbers according to my nurse. She instructed me that I can stop taking Crinone (vaginal progesterone) and Estrogen. I’m 5w2d today. Does that seem too soon?

I expressed my concerns but she said my numbers were nice and high and we would test next week and if there was a bad drop they would tell me to go back on it. Just seems a bit risky to me.

With IVF when did you stop your progesterone?
