"nexplanon is the first birth control i&rsquo;ve ever used. i&rsquo;m 25. my boyfriend and i simply wanted to most effective birth control method. i am a fairly chill/nonchalant/level headed individual.  i had nexplanon implanted 9 days ago and i literally cannot control my emotions at all. the mood swings are outrageous. i&rsquo;m literally irritated about everything, that turns into anger, then it turns into crying because of the frustration of the mood swings. i&rsquo;ve read that it can be this way with any birth control method but my gawd did i wish someone would have told me before i had it implanted. i had my period the week before it was implanted and i&rsquo;ve experienced no irregular bleeding yet. if the bleeding is ridiculous then i will have it removed."
