Here's a great article on the subject: http://www.babycenter.com/0_how-to-tell-the-boss-youre-pregnant_454.bc

As far as the time off, this is what I would do - and did when I was in that situation. I did everything and I mean everything - I could to make the transition easier. I didn't leave anything hanging. I made sure everything was organized, etc. If there will be someone stepping in, in your absense, who doesn't already know the job, do what you can to make that time easier for them, train them, leave them cheat sheets (typed up notes for procedures, etc.). As far as how much time you will take off, if you suspect you may end up staying at home and not go back, try your best to make that decision before your maternity leave (just my opinion). If you definitely plan on going back, let him know it will be 6 weeks up to _____ and give yourself and him a maximum time, so he knows what he is dealing with. The easier the transition and more concrete plans as far as your maternity leave or whether you will decide not to come back will greatly help him to be more accepting of the transition. If you do all of this, and he is still unaccepting of it, then this is not the right boss/job for you. Remember that an employer doesn't have the right to discriminate based on pregnancy or children.

Also, this may be hard because I know there will be days you feel horrible bc of nausea, vomiting, back pains, etc. and you don't have much time to work with before you have to leave - but do the best you can (within reason/and without ignoring your dr), learn the job quickly, be dependable, go above and beyond, and try to make yourself an asset there. Especially if this is a job you end up really liking and wanting to keep for the long run.

 I'll be keeping you in my thoughts and prayers hon!
