Almost 34 weeks pregnant: odd/intense bh contractions that remain intense when moving/walking. second pregnancy. last about 15-30 seconds.

Contractions: Those sound like more than Braxton Hicks. They are more intense and last longer. I suggest you go get evaluated at Labor and Delivery. You could be in premature labor.

Contact OB: While it is common to have braxton hicks contractions at this stage of pregnancy (especially in a second/third one), if something seems "odd" or unusually intense, it is ALWAYS best to contact your ob about your symptoms. He/she will decide if observation is necessary.

Call your provider!: Please contact your obstetrician or midwife directly to discuss your symptoms. A direct assessment with your provider is the best way to determine if any further action is needed. Good luck to you and your baby!

Call your doc!: All pregnancies are different. If you are having contractions call your doctor or go get checked.
