My boss won't let me quit!

I've tried telling her that I no longer want to work but she just gets mad and makes me feel guilty about wanting to leave.

I'll be 37 weeks on Monday and I am so uncomfortable doing anything! I don't even make a whole lot ($100 every two weeks, ugh) but again I only work two days a week.

I only have stayed because I absolutely love my job, but now I'm super pregnant and comfortable. Im due February 9th, yet she wants me to keep working until the baby comes, which I don't find fair at all!

I really want to stop working already because I'm scared of going into labor at anytime. Would it be really bad of me to just quit with only a few days notice?

Any suggestions as to what I should do?
