Hopefully you have learned now that all testing and drugs, etc. is a waste of time and money.
Having a period is considered normal today, but it is not normal in the way that girls experience it. What happens is the body uses this to expell toxins and not what Nature had in mind.
I would suggest the only medical thing you ever do again is read my first schooling book, it is written by an MD and he will teach you what your problem is and the simple cure. He will teach you to never, ever seek medical drugs or test the rest of your life, they are based on false science and do nothing good for your body.
You have 2 things wrong, 1) your constipated 2) your starving. Learn how to correct these 2 things and you have done all you can do, Nature will do the rest.
