I hate where I work(help)

So I can't stand my boss, he's always in a terrible mood & I can't stand it anymore. I know what you're thinking "quit & find another job. Simple". But I'm 10 weeks pregnant & once the baby is here I will be a stay at home mom. So my question is, do I stick it out until October or find another job & tell them I'll only be there temporarily? Opinions please!
