After HSG

Chrissy • 30 years old ttc with our first. Married 2014
I had a HSG 4 days ago. I'm on cd15 and I was supposed to ovulate yesterday but I haven't yet. I am having brown egg white CM but I don't know if it CM or the contrast dye. Does the contrast dye look and feel like EWCM for anyone who has had this done?
