I need to vent/long post

I'm 24. Gen z. I've got a 2 year old toddler and am pregnant and due in September with my second. I'm married, have a job, have a decent apartment, and overall am doing ok. When I was pregnant with my 1st I worked at a daycare. At this daycare I told my boss I was pregnant and she told me not to clean the bathrooms due to the harsh chemicals. I also was showing hella early signs of pre-eclampsia so I was sitting down more often. My coworkers( 3 gen z and 1 millennial) were god awful to me. They never congratulated me. I don't expect any congratulations but it just felt weird. Like normally when someone tells you good news the default response is "omg congrats!" Or some sort. Nope. Not for me, I got "wow" with the worst attitude ever. Later on they apparently complained to my boss that I was sitting down too much and not engaging with the kids bc I was sitting down... I was the head teacher of the school age 5-9 kids and I taught them just fine. I remember telling one of my coworkers "I'm pregnant so that's why I haven't been cleaning the bathrooms. Cause the harsh chemicals" Turns out that coworker went to my boss and said "Holly said she WAS NOT going to clean the bathrooms" I ended up leaving that job true to unfair treatment. I couldn't handle it. Now I'm 24 pregnant with my second. I'm about 6 weeks along and I work at a pet hotel. It's a glorified janitor job with the perks of hanging out with dogs. There is a cat room included. It's completely separated from everything. I have a drs note stating to stay away from the cats due to the parasite toxoplasma commonly found in cat feces. It can cause horrific things to a fetus. I sent my drs note to both of my managers. 1 is the general manager and the other is the assistant manager. I went into work today and my coworker(gen z) was telling me something about the cats. I said "ok but I'm not going in the room anyway. I'm pregnant and can't be around the cats". I preceded to tell her about Toxoplasmosis. Yall this girl rolled her eyes and and was like "wow I didn't know about that" talking about the toxoplasma. She didn't congratulate me or anything. Again that's fine but it still feels weird. Anyhoo, the girl leaves and I shit you not not 10 minutes later I get a nasty message from the assistant manager telling me about how I'm still expected to feed the cats and it's not ok to tell a staff member I'm not going into the cat room. I don't even know what to do with this job anymore. It's getting so unbelievably frustrating and my whole fucking "team" feels like two-faced backstabbing bitches. I also brought up the generations bc it feels like every time I work with gen z and young millennials while pregnant I get constant negativity. But when I work with elder millennials I get more positive vibes.
