I am 16. My period was due on the 24th dec, its now 1st jan. 9 days late. Two negative home pregnancy tests. I feel as if I have period cramps. Help.

Pre-menstrual. It sounds as if you are having pre-menstrual type symptoms. Pre-menstrual symptoms can feel a lot like pregnancy symptoms and it can be hard, sometimes, to tell them apart. Ibuprofen, and a warm bath, will likely help with your cramping. Take 600mg ibuprofen.
