"so far so good, no side effects other than a bit of nauseousness. i did the quick start method, meaning i didn&#039;t start either i the day of my period or on the first sunday after my period. i have no idea if that makes you get less side effects. nevertheless, i followed the instructions used backup for 1 week. after that didn&#039;t use a condom anymore&#039; so i&#039;m hoping it&#039;s effective !!!"
