Hello I just have a quick question, for some reason I'm experiencing uncomfortable cramping before my period. (And my usual PMS symptoms) It's just like mentrual cramps, which I are usual not as consistent as these, but no period. I've never had this problem, I'm just wondering if this normal lol thanks! I've also heard it's an early sign of pregnancy?
