I get migraines and they are almost always related to AF and the associated hormonal changes, using the contraceptive pill helped reduce the incidence significantly although I no longer use it due to other side effects. Have you tried asprin for your headache? I find or my migraines the best thing is aspirin over panadiene forte, ibuprofen, paracetamol. Keeping up fluids also helps

No idea abou the tampons sorry
