i hope i'm not prego/:

so idk what it is. im pretty sure i'm just freaking myself out. but my period ended maybe like yesterday or 2 days ago. but i've been feeling like i have to throw up. and i had some bad cramps this morning. i would get up and i would get dizzy and my vision would turn black but it will come black a few seconds later. and i've been having headaches lately. so idkkkkk
