Is this labor pains?

I woke up from my nap to shooting pain down my back, lower abdomen and vaginal area, bad enough to take my breath away, it happened for a few seconds every minute or so and then will stop for about an hour before it happens again. Problem is that I’m only 26 weeks along, way to early for this. I’ve been under a lot of stress today and probably didn’t drink enough water so I’m trying to relax and drink water right now. Right now I’m just left with a dull ache in my left hip, it’s bearable but painful.
