Did I miscarry or what the hell is going on? (TMI?

So, here's my story. Two days before my period should've started I started to have nosebleeds. I decided to take a test and it came out positive right away. So, when I was 5 weeks and 1 day I went to the er because I had some bleeding. They took a look and told me that there's is a blot clot like thing next to the embryo. That it was normal to have during the first trimester. But, the day after that night I stopped bleeding entirely. Yesterday, I started to have brown/dark brown discharge all day long til last night. It started to have tiny blood clots not big ones and before I went to the er there's was one dime size blood clot in the toilet. Last week my hcg level was 7000 but last night they were at 340. And now I haven't had any cramping besides when I have to go number 2. When I do wipe it's light blood on the toilet paper but the pad I'm wearing has no blood on it and hasn't been since last night too. And when I poop or pee unlike the previous week there's no blood. Only blood on the toilet paper. And no blood clots since. Is there how a miscarriage Is? Or? Because I thought you'll have more blood clots and cramping? Am I miscarrying or is something else happening? Sorry if it's tmi. And it was my first pregnancy.
