Dr appt

Dr office stated instead of ultra sound they will check my
Levels to see how far I am?? I guess that could work right?? I'm pretty sure I'm 6wks so if the levels show less then something is wrong right?? I'd feel much better if they would just look at the baby.. Don't think they will give me the option!! And due to my job I kind of need to know bc I have to be taken off the road at 12wks so my job has to prep where I'm going and have a heads up!! I would like them to check so I'm not going through all this with my job for nothing
