Long term effects of birth control pills?

I have been on birth control pills for almost 10 years. I started them when I was 12 because of endometriosis. I take orth-cyclen which is a one-dose pill. I tried a 3dose pill (ortho-tri-cyclen-lo) because the doctors told me that the lowest dosage is healthiest, but then it started giving me headaches so they changed me back to ortho-cyclen. But now I am concerned because it is a "high-dose" birth control pill. They say there are no long term effects, but since it is a high dose and I've been taking it for 10 years I am still scared! Am I going to get menopause early?!?! Please help! Thanks!
