I need some help ladies! I need to know what I should do in a situation like this!

My manager at work has been talking crap about me around the work place to other employees. Here is when it started... I found out I was pregnant at 9 weeks.. I told my manager the news because I had to leave early due to an appointment. After she found out, she has been such a b*tch. I ended up getting hand foot and mouth with a temp of 100.7 and she told me I had to come into work. She has been wanting me to lift heavy boxes and crates up a step stool and put them on a shelf or stack them in stacks taller than me. I have endometriosis and lately have been getting lightheaded, dizzy with a lot of cramping when I lift too much. So since I don't do it and ask for help she tells people I am "lazy" and just want people too feel sorry for me. I heard she has also called me a "dumbass." There is more to the story but won't get into more detail. I have went to the manager ahead of her and he has not done anything. I would quit but I am moving in less than two months to a completely different state and don't think anyone would hire me for that short amount of time, but I do need the income for the big move. Could I turn her into the business bureau?
