Should I go in or are we okay?

So the past few days I've been having worse cramps than normal. They aren't continuous, they just come and go. When I get them, I get nauseous and dizzy. My fiancé wants me to go into the doctor to make sure that everything is okay, but I don't want to unless I have to because I'm on vacation visiting my mom 2 hours away from where I live. I'm 25 weeks and 1 day if that helps any. I drink a lot of water and have younger brothers that I play with, so I'm active but not over straining myself.
