Has anyone calculated your due date, and then when you go tongue doctor, your further along than you thought? According to this app I'm 7 weeks, but I'm starting to show....is that normal for 7 weeks? I'm 130 lbs, 5'8 and normally had a little jiggle in my midsection...☺️ my mom calls its a little pooch....my first appt is on Tuesday, but I don't have an ultrasound scheduled. It's just to go over medical history for me and the hubs...need some advice!
