Advice please??

Based off my LMP i am 6w4days. However, on 11/19 my hcg levels were only 59. 11/22 they were at 220. I believe I just ovulated late. But The doctor feared i was going to miscarry so i've been trying to make sure the line keeps getting darker and it seems like it is😍. I have my first OBGYN visit tomorrow 11/29. This is my first positive so im not sure what to expect? Will there be an ultrasound?? Is this the time to ask for my prenatal vitamins?? Will there be a pelvic exam? I know forsure i will be getting another blood withdrawal to check my levels again but im not sure what else to expect and be ready for?
