beta 1660?

[kim14]

My beta is 1660 18 days post retrieval. With my son it was 800. Am I having twins??

Hi Kim,

I found this site very useful when we were trying to figure out if we were likely to have twins or not:

http://www.betabase.info

Turns out I was right at the average for twins each time they tested my levels, and at my first ultrasound, there were two perfect heartbeats , so it was pretty accurate. 1660 at 18d is higher than the average for triplets (or more, not wanting to freak you out!) but if you look at the charts there is a HUGE variation in range. I asked my doc and she said the levels are often a good indicator of singleton vs twins but a lot of times she's surprised when a patient she expected to have twins only has one, or vice versa. In the end, you just have to wait until your 6w ultrasound to find out for sure !

Hi Kim. Congrats on your BFP. A high beta like that is very possible to be twins or more. I am preggers with twins and my beta was no where near that at 18dpo. In fact, when I had my first ultrasound I was shocked to learn I had two! Seems they just implanted at a slower rate. But they are healthy and growing normally. So just remember betabase is a guideline, but by no means indicative of the # of babies. Your ultrasound will be the confirmation. Congrats again!

At 20 days post retrieval my beta was 1756 and I am having twins. So, it's very likely you are, but everyone is different and it could just mean 1 strong little bean. Good luck!!

I thought a lot had to do with your increase % as well. My RE told my friend with a huge first number (who had one but totally thought it was two), that beta really needs to MORE than double every two days for twins. But I guess everyone is different. My first beta was 904 at 17dpo, and today it was 1709 at 19dpo. So I guess anything is possible, but I figure that since it didn't QUITE double, that means one. I guess I'll know in 2 1/2 weeks! Good luck!
