advice! third trimester and discharge (sorry about the tmi)

Bethany
So I'm 33+4 and all day today I've had heavy, watery, thin discharge and I've also had a couple of very intense (not painful) contractions. They aren't close together by any means but I just have this feeling that I need to call my doctor in the morning and be checked. Has anyone else experienced this? I've had heavier discharge since the beginning of the third trimester but this is different and more than normal for sure. I don't think it's my mucous plug though but I've never gotten to this point in pregnancy either so I'm not really sure what to expect.
