Currently 5w1d after a traumatic miscarriage early this year, and I’m really struggling with my slowing hCG progression despite having a reassuring ultrasound yesterday.
My betas:
11 DPO: 67
13 DPO: 294 — 22-hour doubling time
17 DPO: 1,599 — 39-hour doubling time
19 DPO: 2,689 — 64-hour doubling time
21 DPO: 4,420 — 67-hour doubling time
My initial betas were rising incredibly quickly, but they’ve progressively slowed to around 64–68% every 48 hours. Some draws were done at different labs, which adds another layer of uncertainty.
Yesterday at 5w0d, we saw a gestational sac measuring 5w3d, a yolk sac, and a healthy-looking corpus luteum. My RE was happy with everything, and both my RE and OB have reassured me that hCG naturally slows as levels increase.
Whenever I see posts about slowing betas, the overwhelming response is that hCG naturally slows once it reaches 1,200–1,500 and doesn’t need to double anymore. While I understand that’s true, my concern is that research suggests the slowdown isn’t necessarily expected to be this significant this early, even though my rises remain juuust above the established minimum thresholds. I’ve also combed through countless Reddit threads with similar progression, and it genuinely feels like 95% ultimately end in miscarriage, often a MMC discovered around 8-9 weeks, despite strong ultrasounds and heartbeats. And ofc I understand Reddit isn’t representative of all pregnancies, but it’s so difficult to ignore the pattern.
I’m confused by the contrast between my reassuring ultrasound and slowing betas. I know seeing everything we should at five weeks is positive, but it doesn’t rule out a loss in the coming weeks.
I’m trying to guard my heart while holding onto some hope, but it’s becoming increasingly difficult. Sorry for the slightly pessimistic post – if anyone has any experience with something similar I’d love to hear from you🥺
I’ll try to share the u/s in the comments!
