are these cramps normal ??

jill

i usually do not get very bad menstrual cramps, but my period is supposed to come in a day or two and my abdomen is literally on fire. i sat down to eat with some friends and out of nowhere this super sharp pain came to plague my lower belly and has not ceased in its persistence since it started 30 minutes ago. it is a very very sharp and constant pain, nothing like the uncomfortable and achy cramps that i usually get. is this normal? could stress be a part of it (it’s finals week)? i could not eat and had to go lie down (and could hardly walk back to my room) because it hurts so badly and i am currently in tears from the pain.
