I feel dumb asking this question, but I've had a couple of false alarms and really don't want to go all the way to the hospital if I don't need to!

I'm having definite contractions (belly getting super tight, then relaxing, in a wave-like pattern) but only mild menstrual-like cramping. They are timeable, but not really painful. I'm sure they're just BH, but should I time them anyway? What if they get to the 5-1-1 rule I've been taught but still aren't intense?

First time mom problems lol...
