Talk to Gynecologist on Cervical Stitch

My dr asked me to get it done because I've a history of a preterm birth. I researched about preterm labor and cervical insufficiency. and according to my research both are different. in cervical insufficiency there are no contractions but in preterm labor contractions starts early. I had contractions and my water didn't break even in the last moment. They had to cut the membrane with scissors. This is all I got from my research. My question is if I had preterm labor is it still important to get the stitch done?
