Am I miscarrying..?

My levels went from 2720 @ 6 weeks with a heartbeat of 104 bpm ,(that night I passed a clot the length of my palm) and had cramping and light bleeding ... 2400 @ 6weeks 5 days with a heartbeat of 176bpm after this day the bleeding stopped and I just gave light Brown discharge

Now at 8 weeks I was told my levels are 1000 with no bleeding or cramping. I’m so confused and my heart is breaking just imagining loosing my baby, I’m trying to be positive but I’m pretty sure this is a case where I’m not going to win.

Thanks for your inputs ❤️
