"i am 30, never had children, and can handle a lot of pain. i have always had very painful periods , i am very sensitive to hormone changes. i love my obgyn ! she is great and fast. that being said it took two try for her to put my iud in. the first time she had to send me home with a prescription to soften my cervix and i was on the end of my period. it is just a very stubborn cervix, she doesn&#039;t like to be touched. it was extremely uncomfortable to say the least!!!!!!!!! both times. however totally doable. the second time we got it in just fine. i had some major cramping but nothing i am not already use too. i was a bit lite headed , my doc told me that would happen. i was fine after a few minutes though and could walk out just fine. i cramped for the rest of the day. the first time my husband and i had sex everything went fine. however 30 to 45 minutes later i started to have extreme discomfort and cramping. four weeks later and i am spotting constantly, extreme cramps, tender sore swollen breast and incredibly bloated. i see my doctor in 2 more weeks. i sincerely hope the side effects go away. because three years without having to take birth control would be nice. if they don&#039;t i will have to have this removed i am in constant pain in discomfort."
