get your OB doc to think of a reason why you can't work and quit for medical reasons. He/she will probably be willing to work with you. I am a nurse and there is always a way to make it work. The fact that you are very stressed, aren't sleeping right, can't eat right, concerned about the baby...There are many excuses your MD could given you to allow you to quit work. It shouldn't be held against you that way. Given it a try! Otherwise, if you quit, just tell them it is because of the pregnancy and you can't give your all at your job and they should understand. Good luck.
