Ghost/someone help: brownish mucus discharge right after FET

[hommy]

Hi Ghost,

I had my FET done on thursday, 2 embryos (Day 3) transferred but in the afternoon I start to have brownish mucus discharge. It's been 2 days since the transferred and I still have brownish mucus discharge on and off. Currently I am under progesterone which inserted through vagina. I am wondering is the the brownish discharge normal? Thanks for your help.
