I have marginal placenta previa. I am 35 week +. When should i go on maternity leave? My parents are worried. They keep calling me. My husband says..since my office is close i can work untill i get pain. Pls advise. My hospital is close to my parents place and its 30 kms from where I stay. Doctor didn't say any date but she said that I should be close to hospital in case of emergency. My husband says that in case of emergency, we can go to any nearby hospital. Which i personally do not want.Pls advise.
