I am 16. I have a very abnormal period, I can get it once every 3-6 months or even twice a year. I been having lower left abdominal pain lately and I don t know what it could be. I been constipated and very bloated. However today when I put my finger in my vagina and applied pressure to the top, it somehow gave me a sharp pain and cramp in my lower left abdomin. I don t know what it is.
