why do i feel this way?

i am constantly feeling sick to my stomach, when i smell food or eat it gets worse. i mostly feel sick in the mornings and evenings, it kind of dies down during the day though. i want to eat because im always hungry, but sometimes even just the thought of eating makes me feel sick... i am only fixing to  turn 16 and i am scared that i could be pregnant but i only had sex yesterday so its too early for the signs. could the worry of getting pregnant  cause this or is is something else? i am in desperate need here and i need some advise will someone please help me?

ur right it is too soon to tell if ur pregnant....so maybe ur causing acid reflux for worry so much? and u are so young, why wouldn't you use protection if ur so worried about getting pregnant? talk to your parents and go to the doctor. its most likely (not 100% sure.) that its you stressing or something like hearburn or acid reflux.
