Twin measuring smaller @ 28w3d u/s

[willsmom]

Ok, so I'm trying not to worry.  I went today for a 28w3d u/s and Baby A is measuring 2 lb 2 oz and Baby B is measuring 2 lb 12 oz.  Also, Baby A approximate gestational age is 26 1/2 weeks while Baby B is measuring on target at 28 1/2 weeks.  At 19 weeks, they were only a couple of days apart.  The u/s tech also said that Baby A's abdomen is measuring smaller than B's but common sense seems to tell me that is normal if Baby A is smaller.  My dh and I are trying not to worry until I see the dr. again next week and the radiologist has read the u/s.  I just read somewhere on the internet that a difference of greater than 20% in size could mean an impending stillbirth so now I am freaking.  Both heartrates were great and they are kicking away.  The u/s tech really didn't lean one way or another in saying that something was wrong.

Has anyone ever had this happen and if so, what were the results?  Should I be worried or not based upon an u/s tech's observations?  Any help or advice is greatly appreciated.  I just can't imagine losing one of my girls.

Thanks!

I've heard that after 14 weeks babies develope at their own rate. If they aren't identical I wouldn't be too concerned it sounds like they are both healthy to me. :)
