I have a stomach ache, i'm tired, i slightly have a headache- whats wrong with me?

ishould be getting my period soon, but i never get that stuff as bad as now. also, i took a 6 hour car ride and had a stomach and head ache after i reached my destination

it sounds like to me that travelling this time did not agree with you. or possibly you are coming down with something. wwhen you were travelling did you get a chance to get out of the car and walk around for a little bit? did you have a chance to get something to eat and/or drink? i'm not sure this has much to do with your period getting ready to start especially since this not normal for your period starting. you may need to see a doctor if it does'nt go away within the next day or two.
