Money Wise (Rant) Help !

I'm currently 7 weeks (almost 8 ) weeks pregnant, and I'm sorta losing it. It's nothing personal, just income wise. I have a boyfriend who currently isn't working, in the one working and every time I get paid I he practically needs something where I have to hand my check over to him so he can get it, idk the last time I got my nails done, let alone my eyebrows that only cost 7 dollars, I'm lucky if I have $6 left to myself after I recieve my check. Last week he needed $300 for his savings, I gave him $500 so everything would be covered just incase, being that I've been extremely sick over the last 2 weeks, I only made $296 this week at work. He needed $300 more because he somehow spent the last one and came asking me for it. Being that I have to pay for my doctor visits because I don't have Mediciaid yet, I had to pay for my appointment, and had to rob my savings to give him the money now I only have $40 to my name, and $5 for transportation this week to and from work, I work 12/13 hour shifts, so most nights I have to walk 3 hours all the way home anyways. He doesn't come to the appointments and doesn't say anything when I have to walk home. If he's not needing money from me, then my mom is lowkey robbing my pockets and saying she'll pay me back but doesn't, she always has knowledge of how much I make because she always needs my check recipes "for her records" I'm having a baby, the appointments aren't cheap, Nobody is helping me out right now, and everyone is depending on my money. What do I do?
