Lost Job @ 36 weeks pregnant. Advice?

So today I went back to work after the holidays and was immediately asked to turn in my key ... I feel like my boss is just trying to get rid of me because he needs to replace me before I go on maternity leave and was looking for any reason to fire me. (His last secretary was also let go at very end of her pregnancy) I’ve never been written up or done anything wrong at work or ever reprimanded for anything, and honestly thought everything was going fine. Well, I’m living in Kentucky 36 weeks pregnant now with my boyfriend (we moved here for his job from Iowa) and hadn’t seen my family or his since moving here this past summer. We just found out my boyfriend’s mom (who lives in Iowa) was diagnosed with a terminal illness and doesn’t have long left to live so we wanted to spend more than just Christmas eve and Christmas Day in Iowa with our family and my boyfriend had time off work to stay longer, so after discovering her illness and feeling heartbroken and bad for my boyfriend and his family, I asked my boss if it was alright with him if I just come back after New Years (which was taking an extra 2 days off and I had time to use for vacation or sick pay) and everything seemed fine and then I got blindsided at work today when I walked in and he fired me. What should I do? Any tips on how I can make some extra income before my baby gets here? Would I qualify for unemployment? I feel like no one is going to hire me knowing that I’m about to have a baby and going to be needing maternity leave soon.
