Trying not to freak out...

Kate
 I woke up around 5:30 this morning with a throbbing feeling in my lower stomach... Luckily we had a delayed opening this morning so I was able to lay around until about 8... I tried laying and sitting but the throbbing was still there and laying down seemed to make the feeling more prominent... I drank a ton and ate a granola bar and the throbbing has decreased but still is coming back. I've gone to pee a few times, no spotting at all. Any thoughts? I'm so scared this is the start of something awful! I'm proctoring standardized tests today so now I'm just sitting here fixated on the pain, terrified!
