My last pregnancy (31st oct) ended up in a blighted ovum.

Customer Question

My last pregnancy (31st oct) ended up in a blighted ovum.
I had betas done 6w4d and they were 3386, in 48 hours they went to just 4700.
The scan on that day also showed an empty gestational sac that measured 7mm (5weeks ish). My levels dropped another 2 days later to 2100 and I miscarried within a few days.
Fast forward to just ten days after the miscarriage and I ovulated and fell pregnant again.
I had my visit to the epu today.
I explained I thought by my o date I was only 5w5d. They still wanted to scan.
My beta Monday (24dpo) was 10,654.
They saw nothing on the scan today except an empty gestational sac measuring 11mm.
The Drs looked all serious and said we had better do a repeat beta, we should see something at that beta level.
They just rang, my beta has gone up to 18,000. I think that's great right? It's a doubling time of around 60 hours.
I said to the dr are you happy with that increase, and she was like "hmmmm no, not really" in a really serious voice like this is doomed! I get the impression because of my mc last month they have written this pregnancy off!
Ive just googled doubling times and when levels are between 1200-6000 doubling time is 72-96 hrs, and past 6000 the doubling time usually slows to over 96hours!
Plus, when the nurse took my blood I said to her, do you want to see it double? She said "we want a 60% increase", well I'm over that!
I could cry now as they've put doubt in my mind 😢😢😢

Once the beta is 10,000, further beta testing is not really helpful. As long as the placenta is working, betas can go very high, even with no embryo.I suspect that your doctor is not happy because another blighted ovum is likely.However, in my opinion, the only way to know is by repeating the scan, usually one week later.If there is still no embryo seen in a week, you'll know that it's a blighted ovum.If the sac was truly empty with no yolk sac, that's also worrisome.I don't think that it's impossible that an embryo will be seen, but I think it's unlikely. I'm sorry.
