Continuing Stomach Ache Naseau, Bloating, Stomach Cramps And Head And Neck Ache Can Be Symptoms For What?

Naseau, bloating, stomach cramps and head and neck ache can be symptoms for what? - continuing stomach ache

I thought you might be pregnant, but I had my period (shorter and lighter than usual, actually), so this option. But I wake up sometimes, nausea and continued throughout the day, headaches and tension in the neck (like blood), swelling and cramping. I've never seen a BM used regularly, so it is probably not clogged. Any idea what might that be?
