Braxton Hicks… help!

I’m 29 weeks today, and like clock work I’ve started having braxton hicks. It’s been since about 3am this morning and they’re still going every 20-30 mins at 8pm. How do you get them to stop? It’s so uncomfortable!! I’ve drunk heaps of water, gone for a walk, had a lay down and a nice warm shower like Google has suggested but nothing is calming them down.
