"i was on the depo provera shot for almost  10 years. i would go for 2 years and off 1. no period at all. had the lilletta iud inserted at the end of april 2017. my doctor explained everything. since i have not had kids she explained that the cervix opening was smaller so there would be discomfort.  it took 5 minutes. a little bit of pain. i had take motrin before my appointment and later in the evening. i was told since i haven&#039;t had a period that i may not get one. my only complaint is feeling bloated and some gas. hoping this goes away with time."
