Do some research online about FMLA, that's the Family leave act. I'm sure it can protect your position at your job for 12 weeks with continued health insurance. You may still have to pay your weekly contribution into your insurance plan.
This appears to be the best plan above as I returned to work at eleven weeks felt I could have done it at nine but didn't want to put pressure on my new hip climbing two floors of stairs as we don't have a lift at work. A lot of pressure to return after four weeks take care.
