Braxton Hicks

I'm 33 weeks +1 and I'm having Braxton Hicks Contractions for few weeks now. But since a few hours I'm getting more regular and stronger ones which last about 1 1/2 minutes. Plus baby boy is crazily active and won't let me rest :(

Do I have to worry about the contractions or is it just a phase where they are more regular and more painful? I was on my feet for quite a while today. Could this cause more intense ones?

Anyone with any ideas what to do?

Thanks in advance xx
