How early will your OB normally sign you off for maternity leave? I've been really stressed lately at work and my health has been suffering. I considered quitting but am going to try and make it as long as I can. I spoke to our HR department and they told me to get a doctor's note to sign me off early and plan it out with my manager. I'm just wondering, how early will the OB sign me out? Is 6 weeks too early?
