Braxton hicks??

Hannah • Mummy to a beautiful baby girl 💕
I've read about braxton hicks so got an idea of how they feel and I'm pretty sure I started having them last week - it's not that they are painful but really uncomfortable and as I'm only 19 weeks in worried why I'm getting them? Will they stress out baby?
I am petite in size so felt my baby moving from just under 17 weeks so know that's it's not that...
Help please!
