Why is COC so good, but the public is so afraid of it? I think it may be the following reasons: First, because of the lack of communication, the clinic is too busy, I also want to talk to you in detail ah, but the next patient has pushed the door into the; so the popularization of science is a long way to go. Second, the media misinformation, what eel ah, pig ah, fish, pig ah are birth control pills to feed the big, eat to give birth to cancer, I just want to say: with the pill to raise livestock, very expensive! Third, many people confuse emergency contraceptives and oral contraception, emergency contraceptives after taking a short period disorders and discomfort increase their fear of all contraceptives. Fourth, in fact, is a crisis of confidence, I will not trust you, you prescribe this and that drug, there must be a kickback!
