Beta Question

[Amy17]

I just finished my 2nd IVF cycle. I had my first beta on 2/9/10 and it came back positive at 467. My second beta was today and it came back at 709. I'm a little nervous that it didn't double. I asked the nurse and she said as long as it went up its good. Has anyone else had a 2nd beta that didn't double?

I would say it just about doubled. Pretty close. Are they doing another beta? 467 is a really good initial #. How many days past transfer did they test? How many embryo's did you transfer? I was going to say it is really high and could mean more than 1.
Good luck to you..!

That happens all the time. Sometimes it signals a pregnancy loss, other times it still goes all the way to live birth. Many women have posted numbers like those on this board and still had a live birth.

One theory, impossible to verify, is that the pregnancy may have initially been a twin implantation, but one was lost very early on. So perhaps the hCG production from two embryos was slowed a bit when only one embryo proceeded. If that happened, we should see numbers just like yours.

My first beta was 10dp5dt and my second was 12dp5dt. We transferred two embryos. I have to wait a whole week for my next beta and two weeks for an ultrasound. I don't know how I'm going to last that long!!

You can see my beta numbers in my signature, it did not double either and I am currently 20 weeks preggo with healthy twins. I had my betas 10dp5dt, 12dp5dt and then a week later too. When my number did not double initially the nurse told me that I probably had twins and lost one. Looks like I proved her wrong! Moral of the story is that Beta numbers aren't indicators of much except that you are preggo! Your number had a nice increase so you definitely got at least one baby on the way. Congrats!
