Could I possibly be prego?! Please give insight, don't just view!

My month is below. I had a few small cramps yesterday but nothing super painful. Monday and Tuesday I felt very nauseous but never threw up. Now today I have thrown up all my food that I've eaten and keep getting hot/cold flashes. Anybody have any insight?? I also took a cheapie hpt at about 5pm today, got a bfn.
