New job while pregnant

Hi , im 20 and have only worked fast food / retail jobs. I desperately need a new job before the baby comes (10 weeks today). It’s hard to find anything because of my experience. My current boss isn’t happy that I’m pregnant and I don’t expect much support from him. I don’t get paid enough here to make it work even with saving every penny I can. I need advice on what kind of jobs I can work without overextending myself. Any advice welcome. I wasn’t raised by parents that knew how to parent and I don’t want my child to go through what I did. I wanna learn how to do it right.
