6weeks - question about betas (TW loss)

I have almost zero symptoms the past few days and very little symptoms overall. So being the nervous nelly that I am I got a beta done yesterday at 6w0d (31dpo). The result is 8619. That number has been in my head all day. It just seems really low for six weeks???

My previous betas were

2/14/26 (12DPO) 31

2/16/26 (15 DPO) 152

Doubling time 28 hours

2/18/26 (17DPO) 479

Doubling time 32.9 hours

Anybody else with numbers like this that slowed down a ton by six weeks? Was everything OK? Anytime I see people talking about their betas at this gestational age it’s like 20,000+ and I’m worried that my last number is low. I had a blighted ovum last time and so I am just so anxious. I’m getting a private scan on Saturday… I’m praying everything is OK
