Quick question about hearing twin heartbeats

post #1 of 11
Thread Starter 
Hi all,
I am just dropping in for a quick question--
Can and do you hear your twin's heartbeat with a doppler? Is that how you found out?

My MW thinks she heard two hb's one in the 130-140 range, the other in the 150-160 range. We spent a while trying to figure it out! Also, according to her measurements I'm at 26 weeks, but will be 20 weeks on Sunday (I was charting, so we know the dates are on, aside from the fact that no hb was detected at the 10week appt.).

Anyway, I was just wondering if your midwives or ob's listen with the doppler. I know this is not a good way to detect twins, so I thought I'd ask over here.

Oh, and she says she'll be able to tell at the next appt. and we'll get an ultrasound then, but I'm thinking I may ask her to just do one sooner!

My OB did not use a doppler. I saw another OB during the course of my pregnancy who did use it, but could not hear independent heartbeats with accuracy. My doula (who is also a midwife) found it very difficult to hear independent heartbeats with a stethoscope too, I guess it has to do with positioning.

I'm guessing most people find out about twins b/c they measure large for their date and then have an ultrasound to confirm.

Mine couldn't hear seperate hearbeats until very close to the end.

My mw could hear the 2 hb, but only after we knew and she was trying really hard. When I went in at 14 weeks and measured 20 she could not find 2 hb, but I went in and got an u/s and there were 2!

My mw was able to hear 2 heartbeats from 13 weeks on. I have heard that it is very dependent on positioning. With what you are describing (2 different bpm's, large measure-for-dates) it sounds like twins are a definite possibility

We could never hear two distinct heartbeats unless they were monitored with a non-stress test (at the end).

We never heard two, except at the NSTs at the end. I actually had a really quick u/s at about 14 weeks that only showed one baby! Still, I wasn't that surprised 4 weeks later to have a real u/s and see two. I was the size of Texas.

hi Louise!
My dr. heard 2 separate heartbeats from the beginning; however, we knew that there were two so we looked for the other. There were always distinctively different rates - although, on occasion we heard an echo of the first heartbeat elsewhere.

You already have two indications that you're carrying twins -- several weeks large for dates and a pick-up on two distinct heart rates. However, neither is the most reliable way to detect twins -- the ultrasound is.

Will knowing now vs. at your next appt. change anything you're currently doing already, e.g. will you change your diet or be more concsious/pay attention to "silent" contractions, etc.? If there are changes you'd make, you may want to bump up the date of the u/s. (Why wasn't that suggested when 2 separate rates were heard, anyway?) If you'd change nothing, it probably makes no difference...

Did your U/S find one or two?
