Am I the only one who feels like birth control pills are unhealthy?

I am sexually active. But I feel like sticking to spermicide and condoms words well enough for me. I've been told by many people that the pill is a better option. But in my opinion, they just seem so unhealthy. I think a period is nessicary, theres a reason why women have it! It starts a new cycle and its just mother nature taking its course. I think anything that prevents you from having something as natural as a period isnt too good. I hear becoming infertile is a small risk too. It really doesnt bother me that so many women take them, to me they are wrong. They seem to be mostly made up of hormones. Is my opinon wrong? For those of you who take them, whats your opinion? Id just like to hear from others. (:
