I don't know if it helps at all, but ultrasound checks for uterine lining are kind of rough b/c there are a lot of various issues that don't show up well on the ultrasound and need further testing. I used to get the wand up the vag a lot and then have to go for more tests. So, hopefulllllllly it's just something like that where they need to investigate further.
