Job hunting while pregnant

Unknown

Hey guys so about a month ago I started a new job and they give me a certain amount of points for 2 months until I'm accepted into the union (in month 3) and considered a permanent employee of the company.. if I exceed the limited amount of points then I get fired and I'm not accepted into the union. I don't get very many points and at the end of the first month going into the second month I found out that I was pregnant. I told the important people at work just to give them a heads up such as my supervisor, the first responder guy (you never know), and the HR lady. I had a gyno appointment for last Friday and I tried to reason with HR and ask her if I could negotiate a way so I can maybe bring in a doctors note and be excused for the appointment simply because of my circumstances and she said no points are points and you will be terminated. Every hour I'm not at work (8 hours) adds up to 8 points which was just enough to get me terminated if I went to this VERY needed appointment. I even showed her the hours when my gynecologist was open which was during my exact work hours and the only days I had off of work were Saturday and Sunday and that's the only time the gyno wasn't open. It's a far drive which I explained to her but she didn't blink an eye at the matter. Long story short I went to that appointment and was fired after. Now I'm in search of a new job but I'm very overwhelmed on where and what job. Being a cashier at a store would work if they didn't make the cashiers unload shit from the trucks and stock shelves with heavy crap that I was told not to lift to that amount of weight. Contacting a temp agency would also work if they didn't put me in a factory which would require me to do the same type of lifting. I shouldn't be around chemicals and constantly breathing them in all day so there goes industrial cleaning/pumping gas all day. Due to my conditions and what I have for job experience hm being very limited on what to do rn. I vowed to myself to never go back to the food industry because I honest to god wanted to kms working as a cook not alone a waitress (no joke). I've been looking everyday on Indeed and all the things I'm limited to do is basically what people are looking for in employers. So I gotta ask what did you guys do for jobs when you were pregnant? Do you know of any jobs that don't require me to work with chemicals or heavy lifting?
