even if she is 23 weeks she could still have contractions and go into actual labor

But your profile says you're 23 weeks that's way too early even if you delivered a premie before.

if you feel contractions it's is probably BHicks. you are probably dehydrated.

I went into labor with my son at 31 weeks and had him at 32. @californiahaley

You're way to early for contractions if they aren't BH go to L&D to be monitored.
