Contractions or Braxton hicks?

Leah

Today I’ve been a lot more crampy than usual. Around 5:30 I had sharp cramps and my belly felt tight and had a burning pain in my lower abdomen and also had back pain. Lasted maybe 1 min maybe less and went away, then it happened every 30 min for 2 hours. Went away for an hour and now is back. I’m 38 weeks today with my first baby.
