Looking for a new job

I’m currently 10 weeks and 6days pregnant I’m currently working as a fedex driver but I’m over the heavy lifting and overworking they’re putting me through. Any suggestions on jobs I should try and apply for I swear I felt like I tried to apply everywhere but nothing seems to call me back :(

Side note : I told my boss I was pregnant, when I found out around like 5/6 weeks  say this is my first pregnancy. I know that this job is very high with like you know working hard and stuff like that but my boss really doesn’t seem to care because he doesn’t help or send me help to lift these heavy boxes or anything like that so there’s another reason why I’m making this post to try and get help on getting a new job.
