When to take leave from work??

Almost 24 weeks. And I feel like things at work are becoming more difficult each day. Jealousy between co-workers just because of time gone for appointments. Every day something different. Monday I had a check up after work and was sent straight to hospital for high blood pressure. Co-workers took it out on me as if i planned it. Husband wants me to quit. I work in a very stressful dentist office. Monday-Friday 7:30 till 6 sometimes later. Talked to my boss and she insured me she will handel the other co-workers. I just don't know if the stress of a job is worth mine or my baby's health. Has anyone else left a job before maternity leave because of stress and other issues?
