16 weeks and having Braxton hicks..

Hannah • Twin girls born 6/26/15
It's been every couple minutes for an hour or so now, they only last a couple seconds but it still worries me. My mom said it could be normal with twins and I should be okay as long as other than that I feel fine but I'm not sure. I've never been pregnant before and I'm only 20! I'm totally clueless lol I could use some advice and personal experiences
