Ok, I'm supposed to have my period on the 2nd of January (3 days from now) but I've never experience cramps like I'm having right now. They aren't unbearable or too sharp but they are unusual for me. I've had this pulling and cramping sensation on the right side of my stomach only. It's a weird sensation that comes and goes. Have any of you experienced this type of pulling and cramping on one side of the abdomen a few days before your period? What could it mean?
