Thank you for your question. I'm sorry you are in pain.
Bad period pain affects almost 60% of women your age. Period pain can occur just before and during the first few days of the period and disappear when the period finishes or it can start with the period and get worse and carry on even after the period finishes. Distinguishing between these can often help a gynaecologist with determining the cause and giving correct treatment. If your pain is of the first type home remedies can include improving your nutrition by including foods rich in magnesium and selenium such as nuts, legumes, sprouts and fresh fruit n vegetables. Certain yoga exercises can also help. A hot water bottle is useful as are some acupressure points you can look up online. If you still do not get relief or your pain is of the second type it is best that you consult a gynaecologist who can help with the correct assessment and treatment.
