30 weeks pregnant with diarrhea, bloody discharge when urinating, dull lower back pain with what feels like braxton hicks and no appetite. do i need to be concerned?

Ob-Gyn Dr. can check: A 30-week pregnant woman with contractions or back pains can call her Ob-Gyn doctor and go get examined at the doctor's office or at the hospital's labor and delivery ward. The doctor will be checking for preterm labor, which can lead to a preterm birth. At 30 weeks, the pregnancy is very preterm (too early). The goal is to get to at least 38 weeks; it is important to be examined by a physician.
