Had my first ob appointment today, since my last period was weird she didn’t give me an edd yet, going to be getting an ultrasound to estimate dates, she did do a quick in office u/s and found baby and heart fluttering, she’s not completely trained in the u/s field so wasn’t able to get a heart rate but did see it flutter. According to my last period I should be 9 weeks tomorrow and due in May. Should I be worried the u/s didn’t show much? I know she was kind of “concerned” just because my youngest is 7 months old (will be on the 12th) since it hasn’t been a year since last delivery which I guess kind of got in my head and now I’m a little worried somethings wrong idk. Anxiously waiting for the call to set up my regular u/s to find out for sure my due date and heart rate. But here’s the pic I got today. Does this look about right for this far along?
