Hello, I currently had a menstrual cycle that has lasted 4 weeks. I am on no birth control meds and I’m 43. The last 2 weeks have been more blood clots and mucous clots and not a flow. The center of my lower abdomen, above my pelvis is sore (aches). Also I am constantly lightheaded, exhausted/fatigued, and my appetite is practically nonexistent. I have recently been having more hair loss than normal too. And my joints, knees especially ache.
