"right off the bat - the insertion/measuring of the cervix  was the worst pain i have ever experienced in my life.  i have horrible cramps and my tolerance for pain is high. but this pain cannot be explained - i took naproxen before and was on my period while getting inserted. all that &quot;timing makes a difference&quot; is rubbish. it makes no difference - you either feel pain or you don&#039;t.  that being said - this birth control has been great. i am only 2 months in and my body is still getting used to it ie - copper smell, spotting and longer periods and cramping. but i feel like me and there is no weight gain. i recommend for anyone who doesn&#039;t want hormones! i am so against birth control and can&#039;t believe i&#039;m saying how good this one is! definitely recommend!"
