Women's Health NP's, great demand, good pay?

Hi everyone, I am considering doing a Planned parenthod NP certification in women's health. I will have an accelerated BSN and am looking to specialize in women's care. However, I was looking through the want ads and noticed that NP's don't seem to be in much demand. Is this true? Also, just wondering, is the time nd studying wirth it to specialize? What is the pay difference like? My main concern is that I wil have job security as an NP. Any replies would be much appreciated.
