Is It Normal? Maybe Pregnant Idk?

Okay well 2days ago Ive been feeling weird. I Went to bed crying 2 nights ago I dont know why. I Was EXTREMLY dizzy. I have never been dizzy like that. Yesterday I Woke Up UGH With cramps and dizziness. Now today I woke up Gagging I dont kno I was Gagging Ugh. Then I Went downstairs to go eat like a cracker I ate the cracker and 5mins later. I Feel Ewww Like I Cant eat anything. It turns my stomach upside dwn. Like It hurts. I Havent Tested to see if im pregnant or not. But if I Am Pregnant I Would be 5weeks And 6days.
