Can someone help? Tmi pictures

I'm pretty positive I'm miscarrying I go back tomorrow for blood work should give a better idea, but for the background: spotting and light bleeding for 16 days from brown to red to pink (picture 1). Day 17 I had a big gush (picture 2) them spotted red the rest of the day (picture 3). I went to the ER because of a nickel size clot. They said it's a threatened miscarriage and to get blood work. They did an ultrasound and said could really see anything. The morning there was a lot in the first pee of the day and then it was light the rest of the day. I've been experiencing what looks like egg white mucus with the blood (picture 4). This picture is really light but early when I went pee there was a glob of the mucus mixed with blood that was about 6 inches on toilet tissue long no clots. Is that normal?? My HCG went from 15 to 41 to 170 to 148. I have ultrasound with OB Tuesday hopefully I'll get some real answers 😥
