I need advice

Jordan

So i work in a high stress high intensity job but for the past 8 months ive been inside working behind the scene well the past two weeks they have started making me work outside lifting 50-80 pound objects multiple times a day in the 100 degree florida weather for 8 hours a day which was fine until i found out i was pregnant ive had a previous loss and im already beyond anxious that its going to happen again i explained to them what was going on and they know about my last loss because i was open about it at my job well all of a sudden they are giving me a hard time and telling me well if you dont want to do it you need a doctors note stating you cant which they didnt do last time but the problem with that is i cant get into to see an ob until September and i tried to go to multiple walk in clinics in my town and they refused me because they dont take my insurance and it would be 150 just to be seen not including any testing they wanna do which i cant afford right now im at a lose to what to do ive debated going to the hospital just to be seen and get a note but i feel bad about doing that i dont have a primary doctor so thats not an option either im so stressed about it which i know isnt good im on vacation currently until saturday so i will need the note by then any advice?
