For the past 2 months I have had my periods but they have been really wierd. I am normally very regular and have light then heavy then light again periods that last 4-5 days. Month 1: I was 4 days late and the period flow was very thin and lasted only a day and half but was severly painful. Month 2: It came a few days early but was mostly brown discharge and seems to be stopping now on a day after it started. Once again it is much more painful than usual. Between these periods and for awhile before the first mentioned, I've stayed constantly nauseated, fatigued, and food hurts my stomach. I was wondering if the nausea, fatigue, and stomach pain were linked to the odd periods.
