Period like cramps at 19 weeks

Kristin • Married with 3 beautiful babies. 💕💙
Is it normal to be kind of crampy this late into pregnancy? The last 2 days I've been feeling like I do before getting my period. My cramps aren't bad but they're in my back and stomach. They come and go but it's definitely not Braxton hicks. I just don't remember ever feeling like this with my other 2 and am getting a little worried. Is/has anyone else experienced this? Thanks!!
