transitioning to a different OB. what would you do?

So my current OB is very rude and I haven't had an appt in 4 weeks (normal I know) I'm 12 weeks right now but last time she made comments like "what do you want me to do about it?" After me telling her I had some vaginal irritation and itching after my Pap. And other things like "I don't like looking at you". So that's why I've decided to switch. 
Since I haven't had an appt in so long , I was wondering if you guys would go to the old OB if your appt was on the 15th just to make sure everything is fine. And then go to the new one on the 21st  OR if you'd just skip going to the old OB on the 15th and wait until the 21st?
