Need some advice/Brixton contractions?

Kassandra
I am 30 weeks pregnant and last night I had some pain on my lower tummy wrapping around to my back went to the hospital and they told me it was just stretching pain nothing to worry about I know Braxton hicks are small contractions but these were not small and lasting a very long time. They sent me home and the pain is still lingering there they say it can be from hydration. Any mommies have advice for me the dr was no help and I still don't have a peace of mind
