5 weeks pregnant, gag reflex but no nausea?

Hey Ladies. anyone else experiencing a strong gag reflex? i'm not even 6 weeks pregnant yet, but i feel a constant (but gentle) urge to gag. i'm not actually gagging, but feel like i could at any moment. yesterday i could barely choke down oatmeal. but tortillas and guacamole seem to be fine *L* anyone have any tips or tricks? or foods that made them gag as well?
