Crinone help maybe TMI

L • Mom of 2 boys. MC. unexplained secondary Infertility. 3 Failed IUIs. IVF cycle started April 23.

So I'm taking crinone, progesterone vaginally. Doc said it would be absorbed by the vaginal walls and the tissue that sloughs off would come out thick bc it's coated in progesterone. I've worn a liner every day since and it hasn't been too bad. Today is 7 days since starting crinone, 9 dpIUI and today I had pink spotting when I wiped. I checked to see if my cervix was low and open, meaning my cycle was coming. It is high and closed. But, I had brown discharge and what must be the crinone come out on my finger. I was surprised ar first and then realized it must be crinone. Has anyone else had it somewhat build up and not come out daily? To insert, I stick it all the way in and push the inserter. Am i not doing something right??
