Contractions.

Daniella
Hey ladies, I am 39+4 & having frequent braxton hicks. My question is - do braxton hicks feel the same as contractions? 
Last night & this morning I have been experiencing ALOT of back pain & pelvic pain. It comes and goes. Aswell as a lot of braxton hicks - I have experienced these through out majority of my late pregnancy however over the last 24 hours I am getting them a lot.
I would just like to get an idea what contractions feel like in comparison to BH's?
Thank you. ☺️
