she very well could be bunching herself up. lol My son constantly did and it can definitely make it feel like contractions or braxton hicks.
well maybe my daughter juss puts herself in the craziest positions in there cause it feels like she balls herself up in there @pixiestix
you can get them anytime throughout your pregnancy, but they tend to start up later on usually close to your due date.
I never had them with my first two pregnancies. I get them consistently now, they started around 17 weeks.
