Is it Braxton Hicks contractions??

I was at work yesterday and all of the sudden my entire stomach felt tight and it was really painful and it didn't feel like cramps. It lasted for a minute or two then slowly diminished. I then woke up this morning with extreme back pain, I felt like my entire back was cramping up and I've been in the bath for about an hour now and it has gone away a little but still slightly hurts. Are these normal pains or should I give the doctor a call?
