Should I stay or should I go? Please help!

Should I leave my job and risk financial harm to my baby or stay at my job and risk physical harm to my baby? My job has me so stressed out that I am an emotional wreak almost every day. At my company you are assigned clients to see each day and you are paid salary. You're expected to make a quota each week which is 25 hours. My company doesn't have any referrals so I currently only have 4 clients (most people need 8 to 10 to make quota) and therefore I am not making my quota but still getting paid as if I am because I'm salary. It sounds awesome but it's not! Because I am not making quota I am forced to do things like go to my office and do work where I can be seen by a supervisor to prove I am doing something work related..if I don't I'm forced to use my leave time for days I don't see clients in order to get paid. I don't have enough clients so l can't work everyday because my company isn't giving me what is needed to work everyday. And because of this I feel they are punishing me even though it's not my fault. They constantly email me even on my days off to ask why I didn't see a client on this day or that day, they make me make up written plans on how I plan to get my units while still not giving me anymore clients. I feel bullied, and defeated and all I can think about is how my stress must be affecting my baby. My heart rate is well over 100 not just because I'm pregnant but because that's how anxious I am everyday. And there are a number of other anxiety related symptoms as well. This can't be good for me or my baby! What should I do? Should I leave my job or stick it out? I'm due March 5th but I'm taking my maternity leave February 1st for sanity purposes but also because I am at risk for going early because I had some low blood levels on my sequential screening. No matter what choice I make I feel like a bad mom. I've tried applying for other jobs but no one wants to hire someone who is 5 months pregnant. I went to college, I have a bachelors degree and I'm stuck at a job that is not only not in my field but is crushing me emotionally everyday. I don't know how much longer I can take it nor how much longer my baby can take it! :(

Any advice is welcomed, please comment with suggestions!
