Contractions or BH? PLEASE HELP

Jessica
Feeling like cramps to the lower part or my stomach (like period cramps) that have been on and off for an hour I don't know if it's the real deal or not . My mind has drawn a blank . I'm due tomorrow I don't have any back pain , the only way to describe it .. Is like mild period cramps . I have drank water , got up moved around and they haven't gone away . They come and go .. Someone please let me know if what I am feeling is contractions or not .  My daughter is moving as this is happening too
