how far along are you? Doubling times vary depending on how far along you are. I understand that doubling times are measured across a 48 to 72 hour window up until about 6 weeks (4 weeks gestation). After that the levels of HCG production (and their doubling time) slows considerably.
I dont want to offer you false hope but i totally wouldnt write this off yet. Can you get another beta taken?
I did a lot of research on hcg doubling times when I was pregnant with dd after being told I had a non viable pregnancy and she was either a blighted ovum or a mole..in 48 hours my levels went from 1560 to 2000 and I was told to prepare for the worst..but I held out for a repeat scan 10 days later and she was fine...my understanding is that levels can take 72 hours to double and up to 96 hours to double once levels are over 6000..also in 10-15% of normal pregmamcies, levels will be low and not increase as expected.
my LMP was 26th Jul and from the scan i had the sonographer said there was what appeared to be 4 week gestational sac on tuesday. well actually it looked like there were two of those. they are rescanning in the morning
i really don't feel like this is an ectopic....zero pain zero bleeding...and levels going up not down so surely can't be MC I think i just need longer to double....the hcg calculator that we found said it would be 3 days for my levels to double...thats ok isn';t it???
could have written memorylapse's post virtually word for word! went through similar when PG with DS, notes actually said ?ectopic, but all turned out well. best wishes for the scan tomorrow. did you have an internal scan, as they show a bit more than an abdominal one at this stage....
Boodle..bleeding stopped and Ive been hurling for Britain today (really hoping this is a good sign)..we will both be on tenterhooks until after our respective scans tomorrow..keeping everything as tightly crossed as possible for you <<hugs>>
