I'm very worried. In the last 6 months I have had 5 irregular periods where I have with had heavy bleeding or very little bleeding. I have also had intermenstral bleeding 5 times where the blood is brown and clotty. Just about 3 weeks ago I started having this sharp pain like a stabbing pain in the very low part of my abdonen which has now changed to a throbbing pain. My doctor has scheduled an appointment in two weeks but in the meantime I am so nervous. I'm so tired all the time and with my fifth intermenstral bleeding that is dark brown and this throbbing pain in my left ovary, I'm not sure what to think or feel.
