IUI questions...

Catt

Had an <a href="https://glowing.com/glow-fertility-program">IUI</a> procedure on the 15th after taking Letrozole and a trigger shot. I am supposed to go for a blood test tomorrow to check progesterone and then a blood test next week for pregnancy. I would rather not go to the lab right now given the covid19 scare. How important is it to get this progesterone test?
