It can be hard to see anything in an ultrasound that early! Everything's probably fine, just wait a month or so. Your doctor will make sure to let you know if there's anything to be concerned about. Good Luck! :)
my 1st u/s was at 8wks n saw a little gummy bear. Its too early to see anything
It may be too early to see baby. Do you go back for another ultrasound soon?
