went in for my obgyn appointment and i’m supposedly 8 weeks and 1 day, last week when i went it we couldn’t see a sack or anything so this appointment we finally saw the sack but no baby, the sack definitely got bigger than before but there’s no baby inside, when we looked really close on the ultrasound Machine it looked like we can make out a little baby but couldn’t get it on the photo. Is everything okay? should i be worried ??
