"i am 21, no kids. on my period i came in to my obgyn and she numbed me up on the inside and proceeded with the process. i will tell you right now, it was the most painful 15 seconds i have experienced. it felt like your worst period cramp x15. when she was done the pain dulled but never completely left. i had bad cramps for days. along with cramps i had diahrrea for the rest of the day and bleeding for the next 3 weeks. the only thing that stopped the bleeding was more birth control! cramps are severe and haven&#039;t stopped in the 2 months, and get as bad as the insertion feeling. my nipples are so painful! i have to wear a bra 24/7 to stop the pain! worst part? sex has become very painful. had an ultrasound, everything is &quot;perfect.&quot; not for everyone!"
