Is it bad I want to quit my job after 3 weeks?

I just started a new job in a new town 3 weeks ago but I don’t feel comfortable here. Some of the people I have met are nice but there are a lot of cliques and mean girl mentality here. I just don’t feel like I belong and not being heard. I’m also pregnant and don’t need to be in a stressful environment but I do need money. What should I do?
