Pregnant?

Ok so my period is now 5 days late. Every test I've taken is negative. I've been dizzy all night with a very low grade fever, and then (this never happens to me ever) I was watching a horror movie, feeling kinda crappy but not queasy, girl in movie rips her nail off, I hurl everywhere. Then immediately felt fine again. I just don't know if I've got some kind of bug or if I'm growing a tiny human. I've never been pregnant so I don't know how morning sickness really feels. Also I can't stop eating lol. Advice from women that have been through morning sickness please??? Ty
