Braxton hicks?

Shawndrea • July 2016 👶🏾 I will meet my son 💙
I'm only 22 weeks and I just expierenced a Braxton  hick . Well I googled how it feels which is a tightening feeling in the stomach . Is it too early to expierence this? Is it normal to expierence it now ? Is it a bad thing as of now? Will it effect the time my baby comes ?
