I had an ultrasound today to confirm pregnancy is in the right place and get an estimate on GA but based on my calculations and tracking on Flo and glow I would be 5w6d today but ultrasound measured 5w3d, which in itself is no big deal, but what concerns me is we couldn’t see anything in the sac with vaginal ultrasound in Dr office. Has anyone else experienced this? Doctor didn’t seem at all concerned and said at next appointment on May 26th we should see a full on baby and heartbeat. HCG levels yesterday were 8023 which she was very pleased with.
