I have had very painful periods for many years. I cannot even get up I have bad cramps abdominal pain and lower back pain swelling over abdomen and my eyes also get swollen.. Also very very heavy bleeding with large clots which is again very painful. I am almost on bed rest for the first three days of periods can't walk properly due to heavy flow and so much cramps pain. Also vaginal discharge is very thick and has odour. And now I have had a severe problem for the last two months I have gone through the menstrual cycle for the 4th time now with very heavy bleeding. I am very concerned.
