High HCG, low progesterone at 7w+2d

I had an ultrasound at 6+3 and Baby was measuring a day ahead and had a heartbeat of 122! The next two days I spotted. Then it stopped for two days. No cramping.

I went and got my bloodwork done at 7 weeks and my HCG levels were over 80,000 (was speaking to medical asst and she wouldn’t give exact number) but I started spotting again at 7+1 and called doc and they said progesterone was at 6.1 (super low 😕) and I started progesterone suppositories last night. I hope I didn’t wait too long to start. High HCG, low progesterone, and strong heartbeat. Anyone else been through this or have some insight ?
