I've been on 3 different birth control pills Zovia (caused me to be on my period for 3 full months), Microgestin with slightly lower estrogen levels (caused me to be on my period for a month straight) and Microgestin 1/20 Fe with really low estrogen, which is what I'm taking now. It has caused crazy mood swings, depression and I've been on my period twice in one month. My doctor said to stick with this pill for 3 months, but I really don't like it. I was wondering if it would be safe not to wait it out for 3 months and to switch to the Nuva Ring. The doctor said I'm not giving my body enough time to adjust, but I don't want to go from an irregular period (my "normal" period lasts from 8-9 days, is super heavy and i miss them sometimes) to another irregular period. So, do you think it would be a wise decision to try the Nuva Ring?
