What does it mean when your having lower back pains and front pains at the same times with cramps at 33 weeks pregnant?

Contractions: They may just be "braxton hicks" or mild practice contractions if mild and less frequent. This could also be labor if strong or frequent. A rule of thumb for 33 weeks...If more frequent than 6-8/hour see your doctor or go to labor and delivery to determine if this is labor. You may try rest and hydration. If it stops then i would not be concerned. The baby should continue to be active.
