"been on various birth controls since i was 15 due to painful periods and anemia. my first 2 experiences with birth control were with the pill,  i was on the 3 month kind for around a year, and after the first cycle i had constant spotting, and on my final scheduled period before changing i bled so bad i passed out . never had kids before, and i&#039;m a very tiny person( 5&#039; 5&#039;&#039; and 105lbs ) so my doctor was slightly worried about the pain, but we still decided this iud was what we wanted. i&#039;m going to be honest, it hurt like anything to get put in, and i did end up throwing up a few times throughout the day, but after day 3 i was fine. been 3 months now and i&#039;ve had no period and never been better!"
