Thinking of taking a trip

Maria
I live in Vegas and I wanted to go LA  which is only about a 4 hr drive. I won't be going till maybe April 22nd which would put me at 32w 3 days it would only be for the weekend  . Would you think I'm taking a risk since this is my 4th child and I been having minor cramping in my pelvic area. Or should I just cancel completely.
