What do Braxton Hicks feel like?

Haley • I'll be 18 in a few months with an unplanned pregnancy, but i believe everything in life happens for a reason, God will never give you more than you can handle. May God be your guide💜
That probably sounds like a stupid question but I've heard about them and my friends that have had baby's have even tried explaining but I just don't understand. Do they feel like baby hiccups? Like can you feel your uterus contracting? Please help.
