First US tomorrow.

Kaitlyn
Hey, I will be 8w2d tomorrow and it's my first ultrasound. I have been to the dr once to do blood test to confirm pregnancy and get me nausea meds but that's it.. I have super bad anxiety so I am just nervous as what's to come tomorrow.. What should I expect? My bf will be there with me I am just still very nervous.. Can someone give me the run down of what normally happens during this appointment? Thanks!!
