@lucia398 With my two older children, I never had betas, except one to verify pregnancy, so I don’t know how those rose. 10 years later we were dealing with secondary infertility due to a trauma my husband had, and so beta hell became a thing. My first pregnancy, my numbers doubled until about 700, then just started to rise, but didn’t come close to doubling. They just kept slow rising. Barely made it to 2,000 (before an ultrasound could should much of what was going on). They kept telling me “sometimes numbers go stagnant around 2,000, remain cautiously optimistic”. My first ultrasound at 5w2d, showed a gestational sac, a tiny tiny hint of yolk sac, then we did see fetal pole and heartbeat at 6w2d. I can’t recall the heartbeat then, but at 7w, it’s was 178, which seemed really really high. I ended up spotting shortly after 7w, and miscarried right around 8w. My second one was a chemical, but I didn’t even get to 100 before I suspected ectopic and went to the ER, where they confirmed there was no pregnancy (anywhere), anymore.
I do know they look for a 50% rise with my clinic, so it’s not always doubling they look for (according to them).
I do hope this is still a good outcome for you, though. I know I read everywhere of people saying it does slow at 1200 and beyond, it just wasn’t the case for me ):
