Feeling sick as hell.

so this happened yesterday too. I would eat a fiber one bar and my body will instantly reject it. makes me so sick. I was abke to eat them fine a few days ago with no nausea but now when I eat them it makes me sick. see I was trying to have my avocado salad but my avocados weren't ripe yet :( so ate a fiber one bar instead because I have to take something with my vitamins. behold Nausea. now I ciuld chalk it up to the vitamins but they never make me feel sick and also when I had on of a fifferent flavor yesterday and way before I took any vitemins. it made me feel sick. this is one symptom I know isnt I my head. not saying its pregnancy but its something. unless my body is just sick of fiber one bars or something they even taste worse than remember. do you guys think this is a pregnancy symptoms or something else? I am now 8DPO
