could I be having a kid soon?

So allllll day yesterday I was cramping like crazy! Back was throbbing and my contractions were really strong and close (even on my medication that's supposed to stop them) I felt like I wasn't getting a break from any of it. When I finally fell asleep at 1 I just kept waking up to pain over and over and over again.... well I'm officially awake and I'm cramping again and just feel like I'm reliving yesterday, does anyone know what might be going on?
