Is it normal to cramp for multiple days during implantation?

Taylor
I ovulated on September 26-Oct 1st. 
​We baby danced on the 26,27,28th and for pass 3 days I've been having some cramping and right pelvic pains. My AF is due Oct 14th so I don't think the cramping is PMS.. Is it normal to feel these pain during implantation? Is that what that is? I mean that's what I hope it is ? but I was wondering how long it normally last and if its even possible to be implantation.
