i feel pregnant iv taken a home test but it came back neg

I think its definitely to early for pregnancy symptoms. They usually start showing after 3 weeks at least. So I think there is nothing you should worry about, I mean even the test is telling you that you are not pregnant. However, you can always take another test but this time make sure you take it first thing in the morning when you wake up for the most accurate results. Also, have in mind that there are other things that could cause such symptoms and menstrual changes. Things like flu, medications, drugs, stress and anxiety. Hope this helps
