Braxton Hicks?

Tiffany
So I think I'm just having Braxton Hicks. But I'm getting some contractions every 5 minutes that last between 30 and 45 seconds. Some are a little painful and the others just feel like my uterus or stomach is tightening up. Is this normal or should I go to the hospital? I'm so freaked out and paranoid. I'm only 29 weeks and 3 days.
