Fired for Ghost Emails and Printer Paper

I'm a little over 6 months pregnant. Wednesday our boss called each of us in to hand out w2s, he was just fine...joking with me and asked how I was feeling. I had a vacation day scheduled for yesterday since I had 3 Dr appts. I woke up to a text from my boss asked to please call him at the office when I had a chance so I called right away. he said there were emails I didn't do?? I got maybe 10 emails a day and what I couldn't do myself I sent to who could. then said I quoted someone wrong (I worked as an executive assistant for an insurance company) which I don't know how I could have done. I've always quoted the same for everyone unless instructed otherwise. I'm not a licensed agent so I could take the information and run through the system and then give to an agent. Then he brought up for the second time that the ONE time in 2 years I forgot to check his printer and it was low on paper, I had already apologized once in person and when I said sorry again, he sarcastically chuckled and said "are you!?" I'm freaking pregnant! yes, I have become a little forgetful but to be that way over printer paper... then he said well I think it's best that we consider yesterday your last day..

I'm balling. he's just silent. I finally said thank you (I didn't know what else to say besides thanks for being a jack ass)he said you're welcome and hung up! now I'm out of work three months before I'm supposed to have baby, and I have no cash coming in until then.....what do I do!?
