Not liking my care

Has anyone else have a OB who requested to have a transvaginal ultrasound after day 4 blood results? I feel like my nurse isn’t really to familiar with this whole process. I thought a raise in levels on day 4 post Methotraxate was normal. Why are we ordering an ultra sound? Then she states for me to get blood work drawn again tomorrow since that would be my day 7 when in reality my day 7 isn’t until Thursday. I just feel like I need to speak up before they continue any further treatment. Isn’t day 7 we should be checking for blood level drops and then following next steps? Does an ultrasound show HCG levels?
