I can't offer much advice but just wanted to say that as someone getting ready to start an FNP program, the programs I have talked to don't expect their candidates to have adult, women's health, and peds experience. They know most people getting an FNP will probably work with either adults or peds, not both. Therefore the RN experience seen coming into these programs is just as varied. Some of my FNP student friends have exclusively peds experience, while others have exclusively adult experience. I am the rare FNP student as I have both pediatric and adult med-surg experience. Good luck with whatever you decide, but I definitely feel like with your experience and GPA you could be a good FNP candidate.
