Girls! Today is 18 weeks + 3 days (according to ultrasound, one day less). I feel it right now, it's tickling from inside, first two fingers below the belly button and on the right side, then another 1-2 fingers below ? Is this baby?? or intestines (they have been constantly rumbling lately, something is running around, but here it's somehow different) Is this "it"? ???
