I believe who ever said if you want t o be a MD , be a MD. If you want to be a NP , be one. I am also pursuing to be a NP. And like you I did pre-med, But sometimes life has a way of taking you in a different direction. I think someone said you don't have to be on call. Maybe where they work, but where I am , the NPs and PAs are on call. You should pursue , if you truly want to, to be an MD while you are this age and haven't the obligations of husband and babies. Now having said this, there are going to be some changes for NP. Soon ( not sure the exact ) you will need a PHD. Check with your state's board.That being my 2 cents. I wish you the best of luck .
