33 weeks pregnant with pelvic pains and previously gave birth via cesarean section, should i be worried?

Contact Ob-Gyn doc: A 33-week pregnant woman's pains might be contractions so should call her Ob-Gyn doctor to see if an exam is needed in the office or the labor and delivery ward. The doctor will be checking for preterm labor, which can lead to a preterm birth. At 33 weeks, the pregnancy is still preterm (early). The goal is to get to at least 38 weeks, so it is important to talk with one's Ob-Gyn doctor.
