Hi, The symptoms you describe could be a wide variety of things. One of the things that it may be is Endometriosis. This is somewhat common. It can cause the amount of pain you are having and passing clots as well. If you have not been to a Doctor for these symptoms I really think you should go. You should not have to take that much ibuprofen for the pain, and the pain should not last that long. It is probably an easy diagnosis, but one a Doctor will have to make. Take care.
