For for not uncommon problems probably. You might want to factor in whether your new health insurance has kicked in.
For something egregiously heinous (according to some definition), don't feel bad about leaving before then.
I left one job after six months. During that time there were three CFO's. The fedgov raided the business and seized the owner's race car, on display in the lobby.
Those were not the reasons I quit.
