What is the most effective birth control with the least side effects?

There's no certain pill you can take that won't have certain side effects.  It depends on how the hormones in the pills react with your body.  All birth control pills affect people differently.  You just have to find one that works for you.

Ive not had the one that you have talked about but I have tried a few pills. Out of all the ones I had Cilest was the best one. I had no side effects at all with this apart from a headache the day before I started a period which is about normal for me anyway! Hope this helps.

Abstinence is the only birth control that offers what you are looking for.

I have tried the mirena IUD and I had to have it removed 3 months later because it gave me chest pains. I have tried the shot for a year and I had to get off because I gained alot of weight and it made me go insane towards my husband.. I tried ortho tri cyclen and it did the same thing... I am one of those that cannot have to much of one hormone.. I am now taking YAZ for 2 years which has the less hormones of all birth control and it has 2 hormones to keep your hormones balanced.. I love it and I have no side effects with it.
