Appointment in 2 hours

I'm getting a little nervous go to my first appointment with Maternal-Fetal Medicine in 3 hour. Wasn't suppose to get an ultrasound until the 14 but going to push for one today since I went to ER Friday and have a Subchorionic Hemorrage. Still having some cramping here and there and a little spotting plus I want to make sure the measurements are correct since ER measured me two weeks behind but with a heartbeat Nervous as can be 3 pregnancy first time going to MFM or having a Subchorionic hemorrage.
