First doctors appointment!!😨😍

Jade β€’ Expecting mama of baby #1!!!!πŸ‘ΆπŸΌπŸΌ due 2018

So tomorrow 10/13/17 is my first doctors appointment with my regular physician. Freaking out and so excited all at the same time. But I know that they will want a urine test and possibly send me to get blood work but do you think that with me not knowing when my last AF was (they have always been hit/miss and irregular) do you think they will want to do a sonogram/US in office? Or will the recommend me to a OB?
