Dr not available so I need help.

I have the worse sharp pain in my down there area and I've had this before whatever it is. But right now it's hitting super strong it's hurts so bad And it's such a sharp pain!!!! I don't know what to do since my Dr office doesn't have a phone available. I mean if I need to see him I can go to the hospital he works in an hour away but my husband is at work. I want your advice of if this is just lightning crotch but bad. Or is this a bad sign of baby coming soon. I'm 27 weeks
