Prodromal labor can be painful, come every five minutes and last 60 seconds each. This is very similar to active labor contractions. However, prodromal labor never advances beyond this point. It doesn’t mean labor is coming or that your cervix has started to dilate (open) or efface (thin).

Prodromal labor consists of contractions that can be fairly regular (between 5-10 minutes apart) and can be painful like active labor contractions, more so than Braxton Hicks contractions. Typically each contraction will last just shy of one minute. These contractions are preparatory.
