Hi I am 39 old. I am having problems with my period it is not in tin time ,late or early lasts for 11 days. And after one week or less I start again with a dark brown discharge first then spotting then normal bleeding .No pain ,but the discharge is all the time after or before. I did a blood work with my OB doctor for the blood account , thyroid, pregnancy . All came normal . I am still doing the same . Please help me , Thank you .
