Work 🙁

I need work advice from anyone willing to help. I work at a fast food resteraunt where I have 3 manager. 1 out of the 3 managers does not like me at all and this is why.... So one of my co workers used to talk to my boyfriend about a year and a half ago and that's the managers "favorite person". When I got the job I knew the girl used to talk to my boyfriend but I didn't care. They only talked on the phone once and then they texted all the rest of the time but it never got past conversation so I didn't think it would be a big deal. The next time I worked after they found out he was my boyfriend they were acting funny throwing little comments but I just ignored them. I didn't really care because I'm there for money and I'm not gonna let anything mess that up. So the next time I worked he came to pick me up the girl was like oh you know I used to talk to him, and I was like yeah I know and I smiled at her. About a week later I called out saying I was sick, I had been throwing up all morning, I missed my period, it was just bad and the manager told me oh you need to go to the hospital because I need a doctors note. So my boyfriend brought me to the hospital and I found out I was 5 weeks pregnant. I brought her the doctors not as soon as I left the hospital just like she asked for. And I told her what was wrong with me, that I'm 5 weeks pregnant and everything. She went on and told the other girl who used to talk to my boyfriend, then they both started being really rude to me like bumping me and hitting me with things as if they didn't know i was behind them or something. But I knew it was intentionally so I just brushed it off, being 5 weeks pregnant I didn't want to be stressing over anything. Especially things that weren't worth it. But at the same time you shouldn't treat people like that, so I talked to the manager ahead of her and I guess he talked to her. On Sunday I called my job for my schedule and the manager, one who likes me, told me I had to work 4 until 8 Wednesday. So Wednesday I'm on my way to work and the manager called me saying where are you and I'm like up the street and she's like oh because I told you the wrong time it was 3 until 8 but don't worry I called and told her it was my fault and I gave you the wrong time. So as soon as I get there I clock in because I was been supposed to be there and I put my things down, washed my hands, and I got straight to work. Then she yelled at me and said don't clock in unless I'm ready to work next time and I said okay. Then the other girl walked passed me and pushed me.. So at this point I'm frustrated and I'm like so fed up, then the manager gets in my face, mind you I'm in front of all these customers and I'm packing their food and she said why were you late. And I said the other manager told me the wrong time and she said why you asking her what time you have to work and I was like because she worked Sunday when the schedule got made so I assumed she'd look at it not tell me what she thought. Then she started yelling about how no one at the job has my number and how I'm 18 and pregnant and they don't want to call my boyfriends phone in order to get in contact with me.. But they don't have to, if she calls the same number the other manager called, that's my direct number and my boyfriend is the secondary number.. So if she's calling the secondary before you try the first one thats not my fault, you're the idiot. Then she yelled out some other business about something that happened between me and my boyfriend and it was about a disagreement we had and it did not at all get physical, or else I wouldn't be with him at all no questions asked. But since we live in a apartment the screaming got the police involved and they said they wanted us separated for the night and he could come back in the morning. Since he's the guy they made him leave and his parents live up the street so he stayed there but it was nothing serious at all. Yet she wants to go saying I put a restraining order on him. And so I told her that's not what happened there's no restraining order so she should try minding her business if she doesn't know what she's talking about. And she tried to say my boyfriend told her that. But no I was on the phone with my mom and I was talking to her about a problem she was having and they heard my mom say "it's good you got a restraining order" not knowing she was telling me a story and assumed she was talking about me and my boyfriend. But i was in the bathroom talking, so like who goes out of their way like that just to be in someone else's business. Listening at the bathroom door is unprofessional and childish. It's disgusting. But anyways she got mad she was wrong and so she told me oh you can loose your attitude and I ignored her and kept working. Then she called me and I said yes but I was packing someone's food so I didn't go to her. Then she came to me with a attitude saying didn't you hear me calling you and I calmly said to her that I had said yes. And she told me to come here and asked if I wanted to leave and I told her I didn't care. So she told me to go home. Then she told me to come sign a write up and I thought she meant for telling her I didn't care. Then I look and the write up is for the day I went to the doctors saying I didn't call out early enough. My job opens at 11. The people who are scheduled to open don't get there until 10. I was scheduled to work at 12 and I called at 10 when I knew they'd just be coming in. But she said I should've called out earlier. 6 hours earlier is actually what she wrote. Even after finding out I was pregnant and me giving her the doctors note. But I signed it and I left. Walking to me and my boyfriends place I called him and I was crying and I talked to him and he was really upset. He met me at the house and comforted me then he left back out. When he came back he told me he'd went to my job and spoken to them. I told him that's not appropriate and it's unprofessional cause that's my work place and it'll make me look bad. We have to handle everything the right way I told him. But he was just frustrated that they keep picking at me he said. And he was saying how it's not fair and he doesn't want me to get stressed out because it'll affect the baby and that's not good. And I understood what he was saying but still told him he was wrong. The next day I went to get my check and the head manager was there once again and he told me that he's gonna have a lawyer call me and he wants me to talk to them and sue them. He also told me to go to the doctor and tell them I'm feeling stressed and tell them what's been going on at work so they can vouch for me too. And so I did that. And I was stressed, thank God my baby was okay. But when they found out about what he'd told me they were very upset (I didn't tell them I swear). Now they've told everyone about my pregnancy, although no one cares or treats me any type of way but them. Now she's been scheduling me for 8 hour shifts back to back. She'll do it like 4 days in a row. And I don't know if I'm even supposed to be on my feet that long. I don't know if it'll stress the baby or anything. I have my next doctors appointment the 26th and I was gonna ask the doctors but if anyone knows please feel free to comment. I just need advice on how long I should be on my feet and what I should do about work. I feel like they're pushing to stress me because they want me to have a miscarriage. I just need help. I need any advice.
