I am 23 years old.I am facing heavy menstrual bleeding since eight months.The time duration is 5 days only but its really heavy bleeding and its increasing every time.Moreover,each time i am getting my periods 4-5 days before the date it happened last month.

My haemoglobin level has also lowered and am facing continuous weakness,unbearable pain and numbness in pelvic region.Also,i feel terrible headache.Is this normal?What should i do?Please help.

PS:Since my first period i have terrible pain during periods,but now because of increasing weakness its almost unbearable now.
