Anyone else getting a ton of discharge in the 3rd tri?

I'm 36 weeks pregnant with twins today. Last week at 34+4, I went to the hospital because I thought I was leaking amniotic fluid. They tested it and it was just regular cervical mucus, and they checked my babies and their fluid levels are fine. I've had three sonos since then (with twins I'm going twice a week now) and the fluid around the babies has been fine. But this discharge is crazy! I'm told it's a mix of discharge and pee (two heads on my bladder) but it's freaking me out, lol!
