Discharge...?

Brittanie • Ariel Diana Nichole was born 9/7/16😊 Pregnant with my 2nd 💕
I'll be 21 weeks on Saturday. For about a week now, I've had A LOT of discharge. It looks like normal discharge, except a little more thin/watery like. No blood, no brown, just clear with a white tint. It drives me crazy because my clean pear of undies after taking a shower are soaked with this discharge after about 4-5 hours. I was just wondering if this much discharge was normal? Thanks ladies. -ftm
