Period like cramping - 36 weeks pregnant

Kelly Jean • Mommy 💙💗💛 fiancé 💍

So I am 36 weeks 3 days pregnant. All day I have had period like cramps. I wouldn’t think they’re contractions because they don’t come and go. It has been constant. Should I be worried? Or is it just from her moving down? I’m a first time mom and have no clue what to expect.
