At first this pill was working out great. But now I have been on my period for almost 5 weeks. Dr's nurse assist. said it was fine & not to worry. But 5 weeks? Horrible cramps. That was the whole point of taking this pill. My periods have been horrible my whole life but seem to get worse as I get older (38). Considering partial hysterectomy if we can't get periods under control. Any suggestions or opinions?
