Felt a gush, then brown discharge??

Hi girls,

I’m 33 weeks pregnant and have been having an increasing amount of BH lately. Just now, I got up and felt a gush as though I peed myself, panicked and ran to restroom. While wiping, there was some warm watery discharge along with a tiny bit of brown discharge??? I’ll continue to monitor and give my doctor a call in the morning, but has anyone else had this happen?
