Twins?

Helen
Oh, this is nervewrecking. 
Went to a scan yesterday, and even if he did not say- it looked like to sacks! Going to a followup next week, guessing I will find out then. 
I am googling the shit out of this, and every scan of twins i see is so similar to what i saw at the scan. My scan with my son was very diffferent, with just one sack. 
Have anyone experienced anything like this?
