When can you start getting braxton hicks? Does everyone get them?

Bárbara • I'm 28, and I have a beautiful baby girl born on May 30th, 2017 ^^ I also have a dog named Oliver and I love him lots!
Lately I started to feel some pain in my lower abdomen and I want to know if it might be that, or can it be that the movements of the baby are getting a little painful now? I'm 26w6d and a first time mum so I don't know how braxton hicks or contractions feels, any advice? Thanks! ^^
