Women are frequently in labor before their waters burst; in fact, the rupture might be caused by the powerful contractions of active labor. Women, however, can have their water rupture spontaneously without feeling a contraction, according to Groenhout. This may be due to the relaxation of the cervix or up until now undetected fetal head abnormalities. If you have not delivered yet and think that you might during labor, don't worry about breaking your water beforehand. It's normal and it doesn't mean that you're going into labor prematurely.
