hi, i have been for an intervaginal scan today, 2 gestational sacs were found but they said it was a very hazy scan so couldn t detect yolks in either sac. i think i am 6+2 weeks pregnant & the 2 gestational sacs measured 16mm & 14.5mm. got to go back for a follow up scan in one week. have had one child, then a miscarriage from a blighted ovum & am now worried that this is 2 blighted ovums. if it is twins, is it likely that they are smaller & therefore not showing on the scan yet ? thank you.
