Discharge, normal?

I've been having so much vaginal discharge lately. No smell, just white/clear and I'm not sure if it's normal to have so much cm during pregnancy. I've started wearing panty liners. I'll ask my doc at my appt in 3 wks but it's a bit weird. 
I was on vaginal progesterone for first trimester so all tht junk was always dripping so I don't know if this is new or has been going on for the entire pregnancy. 
Anyone else with lots of cm?
