Tmi!! Yuck..

So I’m 37weeks and 3 days and I have been having this nasty mucus looking junk coming out of me for weeks now. I’ve already asked my OB and she says it not my mucus plug. But she didn’t really check it out either she just tested to see if I had a uti and I’m good to go. So I’m calling on all my mommas out there for answers. Mind you this junk doesn’t come in a tiny amount. It’s always a lot. I think this is the smallest I’ve had it (will show a photo) it’s never bloody or any other color but it’s always this yellowish color. What do y’all think it is?
