My experience with implonon was a fairly good one, I am glad that i did not end up pregnant. I am due to take it out tomorrow so we'll see how that goes I'm kind of nervous. But overall I did not gain weight with it and in the beginning i did not have a period for two years. After my period was irregular and sometimes i would menstruate for almost two weeks. it didn't really bother me. I liked implonon and i might get it again. View Thread
