However, regardless of the method, no singular birth control method is 100% effective. Any claims by any medical company or producer of birth control methods are wrong and are thus unethical business practice. The same goes with preventing STDs. No birth control method can correctly say that it can fully prevent infections from STDs.
And then, of course, there are the myths that you need to go over with your health officer for clarifications. These myths began as gossips and spread and spread until they are accepted as truth while otherwise no proof has been provided supporting these claims. One such fallacy is the birth control pills and gaining weight.
Among the birth control questions, this is often asked: will I gain weight if I used birth control pills? The answer is no.
