How do twin bumps measure in singleton weeks?

agrundman · May 2010

Is there any information available that talks about being however far along with twins equates to looking like a someone pregnant with a singleton at x weeks/months?

I'm just curious. I went to dinner with a friend who is due with a singleton 4 days before me and I'm obviously much bigger than she is so I started thinking about how big I am in singleton terms. Hope I worderd by question clearly.

Thanks!

Around 16w I was measuring 4w ahead, then it got to 6w and about 8w at the end.

I believe twin pregnancies measure 6-8 weeks ahead of a singleton pregnancy. I am 32 weeks and measuring 37 weeks.

Most twin moms measure an average of 6-8 weeks ahead of a singleton pg. Everyone is different so, obviously, there's a fair degree of variance.

yup- this is the average... but of course- it all depends. I measured about 5w ahead with my singleton all the time b/c he was pretty big.

with the twins there were weeks where I dropped a little bit - doc said positioning has everything to do with it- if they turn a certain way the measurment is totally different than just a minute before.

This is what I've read as well, and is consistent w/how I've been measuring.

Dr. Luke also says that at 24 weeks: a singleton mom's uterus is about the size of a football w/the ends cut off, where as a twin mom's uterus is about the size of basketball.

I've been measuring about 6 weeks ahead, it really depends on how they are laying. It seems like when they are both transverse I measure bigger and when they are both head down I measure smaller.

I heard 6-8 weeks also.

That is where I was for the most part, it slows down as you get closer to the end; I was measuring 46 weeks from 33-35 weeks.

Thanks everybody for your input!

At 33 weeks I was measuring at 45 weeks. Guess I am an overachiever

Ditto! I went to a baby shower last weekend for a girl who's due 11 days before me (singleton). I am definitely a lot bigger than her at this point - she barely looked pregnant to me, lol!

At 16w my OB said I was measuring 10w ahead, so like a singelton 26weeker. Scary. He said twin pregnancies measure anywhere between 6-10w ahead and that I'm on target. Still scary.

As others have said, it can vary greatly depending on how you are built. I happen to be very short-waisted, so the babies had nowhere to go but out and I ended up measuring 11 weeks ahead.

I agree with the 6-8 weeks ahead. At my last appointment at 26 weeks I was measuring 34 weeks. My doc doesn't always bother with the measurement b/c it means so little, but I like to ask b/c I'm always curious to see how I compare. Of course, it's not like I can't tell just by looking at myself compared to my friends. Big Smile

Dr. Luke's book says 6-8 weeks ahead; I am measuring 10 weeks ahead.

I started out measing 6 wks. bigger at 11w. But every appt. since I've measured anywhere from 10-12 wks. ahead. Last she decided to check I measured 41 wks. at 29wks.
