Did you have menstrual feeling cramps before more active labor?

LP
I've been having regular menstrual feeling cramps every 7-10 minutes since last night around 7pm, lasting about 30 seconds each. Anyone else experience this? Feels different than Braxton Hicks... Wondering if this it and if so, why it's not getting more intense! Due on Sunday. 
Update: contractions are now 5-6 minutes apart! I'm in labour! Have had some show today as well. Here we go!
