Should I get on the pill???

I'm 14 and have had my period for over 2 years now. But the thing is, I only get them every few months. The longest I went with out one was 6 months. I know it's not healthy to go that long. I've seen 3 different doctors about it and they all say "well just wait and see". Should I ask my mom about the pill? I'm not sexually active and don't plan to be but I would like to know when to expect something like this.
