I believe I may have had implantation bleeding.

What was your experience with implantation bleeding? What was it like and how long? My period is due tomorrow. But yesterday I had some cramping then went home and went to rhe bathroom and there was some pink mixed with cm then pink when i wiped about 3 times. Nothing in my undies. Then felt some pretty strong AF like cramps and thought oh yeah my periods starting. Now that was yesterday at about 4 pm. But now there has been no bleeding since. And no more cramps. Im gonna test when im off work if af hasnt showed but does this sound like implantation to you guys? Ive never had this and am getting my hopes up. Hopefully its my time.
