Braxton hicks???

Chasity

I'm 29 weeks now and just around 2 hours ago I started feeling "period like cramping". Is this Braxton hicks contractions? When I layed on my left side or walk they eased up. And now laying on my left side baby has started moving around a bit. Help ladies, the cramping is still there it comes and goes but I feel like it only lasts a minute and starts 10 seconds later. It feels just like a period cramp. Should I be worried or is it just Braxton hicks?
