"absolutely hate this birth control! the day i got it in my arm bleed for 5-10 minutes before i was even out of the doctors office. then i had my period for about a month so they gave me estrogen to stop it and i just ended up breaking out in hives for a month. i&#039;ve gained tons of weight that i never gained on 3 years of the depo shot. i got it it november of 2015 and haven&#039;t stopped bleeding since about a week after i got it. try having your period for 8 months straight! some days it&#039;s less then others and some days it&#039;s horrible! i would never go back on this birth control again."
