Fetal size differences in twins

Hi everyone!  I am currently almost 9 weeks pregnant with twins from IVF.  Today I had my final ultrasound with the fertility clinic before being released to the ob/gyn.  The final ultrasound showed that twin A is measuring 9 weeks 1 day and twin B is measuring 9 weeks 5 days.  Is this normal for one twin to be superior in size?  I just want to make sure everything is going well!  Any help would be greatly appreciated!

totally normal my twins were always anywhere from 1-6 days appart and just like when they were born they weren't the same size Jacob was 6 lb 12 oz and 19" long and Mekaila was 5 lb 14 oz and 18" long same thing goes in your tummy they are different babies and can be different sizes so they sound great....congrats mommy....only time to worry is if they get over a week appart then they might do some checking and even then everything can be fine

I posted a similar question a little while back.  I am 11 weeks pregnant today according to my LMP.  My twins are measuring 10w 5d, and 10 w 2d, so I guess it's very common.  Although, I'm not really sure how far along that makes me or you!

it's normal. my twins varied in sizes from 1-8 days difference. when they were born baby a was 10 oz smaller then baby b. they were the same for a while and now they're the same length but eli (he was my baby b) is at least 5 lbs heavier then brett (he was my baby a)

Yes, it is common...

Yep it's common, and generally not dangerous, especially (I would think) if they are fraternal twins.  The only time it can be a bigger concern is if you're having identical twins and then there is a greater chance for TTTS (Twin to Twin Transfusion Syndrome - I think is the name of it) That's when one twin can take up more nutrients than the other...  It's very rare though.

My fraternal twins have been measuring a few days apart the whole time, as well...  =)

Congrats on your successful IVF!!  I also conceived from fertility treatments and on my third IUI,   35Mom ~ 18 weeks
