tmi - weird discharge HELP!!

Amanda
I am 35+6 today, and I am having a really weird discharge. I haven't had this before, so I'm not sure what it is. I have been wearing a giant pad today in case my water breaks (it suddenly broke st 37 weeks with my daughter, so I'm trying to be prepared). Baby boy has been SUPER low all morning and I have had pelvic pains from it. I went to the bathroom and noticed a weird opaque discharge on the bad and on the toilet paper when I wiped. It honestly looked and felt like hand lotion or something, but I didn't put anything down there. Has anyone had this before? Do you know what I could be? I will try calling my doctor, but I'm freaking out. I am at work without a private place to talk to my doctor, but will be running out to my car to call in a bit. Please help! Thank you!!
