Miscarriage?? Maybe??

So I think I miscarried 2 weeks ago. Got my first positive test December 20th. December 22nd-23rd I started bleeding really badly...filled up a pad and had small clots. Continued getting very dark positive tests the next week. Got a blood test done which was positive. I ovulated December 6th and the only time I had sex was December 5th, so I should be at least 6 weeks. I went to get an ultrasound done Thursday, and the ultrasound tech said she couldn’t find anything. Got my levels checked and they’re at 94, and they should be at least 1000 at this point, so I think I’m still miscarrying.

My question is this: what sort of discharge should I be having? As it is, I’ve been having very fertile discharge for the past 3 days. Looks like egg whites. Any ideas as to what could be causing this? I’ve still got HCG in my system which is causing pregnancy symptoms and positive tests. Would the fertile discharge just be another symptom?
