OB troubles.

Ok so I don't really like my OB but I am over 33 weeks so I figured I should just stick with him to the end (he doesn't deliver at the hospital I want to go to anyway) but I am supposed to be starting my weekly appointments in the next two weeks and he just told me he is going on vacation for two weeks and he won't be able to see me until I'm 37 weeks! I don't know what to do! I'm frustrated and angry with him. I understand needing vacation but I'm in the home stretch of this pregnancy and went to the hospital last night with signs of pre-term labor. Any advice on how to cope and not punch him in the face?
