I was reading in another thread and came across this comment in reference to beta doubling and was wondering if many of you found it true;
\"told us doubling was single, first number x 3 was probably twins; and if higher we would need to talk.\"
The reason I am asking this is we did FET with 3 embryos. My betas were as follows;
1st beta at 12dp3dt (or 15 dpo) was 892.
2nd beta at 14dp3dt (or 17 dpo) was 2100.
They doubled and then some...it doubled in 1.6 days according to my calculations...but they did not triple.
In addition, I know the beta levels can go either way on how many could be in there but as a reference my 1st pregnancy on 17 dpo was 750. This pregnancy it is nearly tripled on the same dpo. Could something be wrong? It just seems SO high compared to everyone else's. (I have yet to come across someone has high betas so early in the pregnancy as I have. If you have my numbers beat, please let me know! 
)
I go in for an u/s on Thursday and don't know what to expect.
Thanks!
