? I am 20 years old, after I had my IUD removed I have had one problem after the other. I am needing help to find why it has been so long since I have had a period and all my pregnancy test come out negative. Which I don't mind because I am too young to have a baby but I would love to know what could be causing my extreme abdominal pain on the lower left hand side. So if you could help in anyway with advise or suggestions I would gladly take them in.
