Mucus plug before 30 weeks

Hi! I know the mucus plug can regenerate and doesn’t necessarily mean labor is near, but should I be concerned losing a part of it so early on? I’m 28w5d and this is going to by third live birth — with my first I don’t remember losing it and with my second I only lost some after a membrane sweep the day before having my daughter. I know this was part of my mucus plug because of the jelly like consistency and a slight tint to it. I’ve also been having pain in my pubic area the last few days that I don’t remember having before, but it’s more like a soreness pulling feeling though.

I have my glucose test in 2 days, should I wait to bring it up until then?
