severe back pain 😬😬😓😓

I have been having severe back pain in the middle of my back for the past two hours almost. Will be 37 weeks in two days and just curious if I should be concerned? i have already tried taking tylenol and laying down, walking, etc. nothing seems to be working but it is intensifying and getting pretty uncomfortable. I know with contractions its normally lower back so Im assuming its not that but I have been having BH contractions as well. I just need to know what may be the issue or if anyone else has been experiencing this because I cant get comfortable. Thanks ladies.
