Early quick rising betas?

[GamerGirl09]

Hellooo, just wondering if others had experience with quickly rising betas and if all was ok?

So we’re told we wanna see beta hCG levels double in 48-72hrs and anything above 60% rise is okay but I can’t find much online about when it’s higher than that.

My first beta at 11dp6dt was 490 and at 13dp6dt it was 1828 so the double time is approx 26 hours. Anyone else have a similar experience and it turn out ok?

For background, 33yo, did ICSI last year 17 eggs retrieved, 12 mature, 11 fertilised - super poor attrition, only got 2 embryos - one day 5 and one day 6. My first transfer ended in early MMC and so this is my last embryo and I guess I’m just super anxious 🤞🏼♥️ Thanks in advance!

this might be a multiple pregnancy potentially?

@GamerGirl09 yes mine did and I got a strong positive at 6dp5dt on a regular test no early detection, I was concerned multiple pregnancy but a scan at 6 weeks showed only one, I think it can just be how your body produces hcg

So, a lot of the info online about betas is bollocks to be frank. It's true that up to 72 hours can be fine (and occasionally slower can also be fine) but the average doubling time at this stage is actually slightly faster than 48 hours - the 48-72 is bizarre when so, so many people are faster than 48 hours.

Fast doubling betas could be a sign of multiples, but also just a single pregnancy that is going well - it's a brilliant sign and nothing to be concerned about.

Thanks so much everybody ♥️ First scan booked for 23/02 so fingers crossed all okay 🤞🏼
