Should I quit?

So should I quit? My boss hasn't been very understanding with my pregnancy. And when I got the job it was seasonal so I'm not even supposed to be working this long but they offered me a part time job if I wanted it and at the time I wasn't pregnant so I accepted it. now that I'm pregnant I'm just really tired and sick all the time. I don't really need to work anyways I was a stay-at-home wife before, I just got bored and wanted a job I work at Ulta by the way. I'm gonna be busy here soon with summer, so what would you guys do?? Oh and my boss is always rude to me and has a catty undertone to everything she says so while pregnant I want to explode on everyone.
