Is this Mucus plug?

I’m 17 weeks and noticed this discharge today. I’m also on vaginal progesterone every night. Should I worry about this? There’s no smell though. Should I reach out to my doctor. This is my rainbow pregnancy and it freaks me out with every new symptoms I come across. Please keep my baby in your prayers.
