babies sizes by week in 1st trimester?

hello ladies...

I am fairly new on these boards and have a question:

do you guys remember or have written down what your babies sizes were at each ultrasound in your 1st trimester?
my RE always says they look great and he thinks I won't have any problems.

I just saw on another blog hat another gal with twins had 4.9cm and 4.4cm babies at 10 weeks, mine were only 3.12 and 3.24 at 10 weeks, seems like she's much bigger and taller though.

just wondering, is there an average by week or so?

Maybe the other person was measuring ahead? I don't think there is a certain size for them to be- but looking at your measurements, it looks like you have had good consistent growth! I know my RE measured them, but I really don't remember paying much attention. I think I was always in too much shock that there were still two of them!

 

Hi there, I dont have any measurements before 11weeks, 3days - my twins were 4.6cm and 4.5cm (crown to rump) at that time. Then at 13w, 3days they measured 7.3cm and 7.1 cm.
I was supposed to be 10w, 4 days when I went in to get the first ultrasound because of bleeding, and that's when they measured and said that I was a week further ahead than we thought (4.6 and 4.5 was 11w3d - so they said)(yay)
Looking at your measurements your twins seem to be growing well HTH

 

Have a look at this chart on babycenter.com. It's for singletons, but at this stage in your pregnancy it should be fine.

Oooh that's a great link!
Mine were 2.4 cm at 9 weeks 3 days, sounds like yours measured just fine When they do the measurements, usually an estimated age pops up, like "10 weeks 2 days". You could always ask your Dr about that.
