throw up in my mouth ?

Today i just went to use the bathroom to go pee and soon i got up from the toilet, i end throw up in my mouth a little but it fell into the Toilet. happens once in blue moon. I was wondering if anyone else get that? & is normal we throw up a little in my mouth?

i am not like other girls go out and have sex every guy i date please dont laugh for it, go take some where else. I havent had sex since my ex boyfriend i actually keep mine close not to pregnant and clean. i had my flue and corna shots and i was fine no side effect for me, is from what it possible i can eat from last night? i get my periods every month on same time and i am on it now
