Surprise

I was in trigonometry. My seat was still next to Jessica.
Mr. Tambert was starting to hand out papers. Tests to be more exact.
"You may begin. . .now." I picked up my pencil and started.
About fifteen minutes into the test, I felt something wet. I stopped and thought about this for a minute. Only one thing came to mind.
"Oh my god." I whispered, still looking down at my paper.
"What?" Jessica asked me quietly.
Still looking down, "I think my water just broke."
"Ladies, there is no talking during a test." the teacher said in a stern tone.
