Not happy with my employer

I started working there a couple months ago and heres what ive noticed. The dr is an asshole who complains and throws fits when something is done incorrectly. He doesnt try to approach you nicely to correct it. He'll yell and talk shit in Chinese (everyone but me in the office speaks chinese). Im the only front desk receptionist but i cant sumbit claims to insurance. His wife does that and 2 months worth of charts are piling up waiting to be submitted. I took a day off the other day due to my morning sickness and i got in trouble because the wife couldnt handle being a front desk by herself, which was what she did before i started working. Im trying to stay til at least early april (expecting around april-may) for the sake of my sons health insurance but honestly, i dont think i can go another couple weeks.
