Lots of Braxton Hicks at 25 weeks

Been not feeling great the last couple days. Having lots of Braxton hicks contractions and aching in my lower back and stomach. Not sure if my son is maybe causing the aching by pushing a nerve (he's very active) or something but it's been keeping me up at night. My doctor told me at my last appointment that BH are normal as long as they are not regular or painful. I wouldn't say it's painful... more just uncomfortable and achy. It's not been getting worse and has been off and on, usually just aching on one side or the other. I've found baths stop the BH and ease the pain temporarily, so I've been having lots of baths. I don't really want to sit in emerg. for 6 hours to be told I'm fine so I'm just waiting it out to see if it gets better or worse. Should I be concerned?
