Yesterday, 22nd day of my cycle, 5 days before expected period I started having brown discharge, then red bleeding started in the night. This then turned into heavy bleeding and dark, almost black, blood clots and horrible cramping. A friend of mine who is a PA said that she thinks I have had a chemical pregnancy. How would I know if this is true? Can an OB test for this? Do I need to go to the doctor or just let it run its course? We are TTC, so I want my doctor to know everything that is going on to make sure I don't need to do anything or not do anything. Or am I just thinking too much into this?
