Discharge, is this normal? TMI

Kilgore
I am currently 32 weeks with my third baby, I have noticed when I'm up getting more chores done around the house I have a very heavy discharge. Clear, mucus type. I never had a discharge what so ever with my other two pregnancys besides when I lost my mucous plug. Have any of you ladies experience this, if so did you ever find out what could have caused it?
