Where should I get birth control pills?

I'm 25, and still on my parents insurance plan for another 3 months (until Dec.), at which point I will immediatley get insurance through my full-time employer, but it will be a different insurance plan, obviously. I can't afford to change birth control in that time as I'm getting married at the end of January and am not currently sexually active(waiting for the wedding), and I know that the pill needs to be taken in advance for it to be most effective. My thought is to just go to planned parenthood until I'm on my own insurance and can find a doctor without the hassle of switching insurances and such.  Thoughts?
