Cramping three weeks after regular period....hmmmm?

I went off my period which was only three days long on June 3rd. Today is the 19th and I am cramping as if I am about to come on again. Fiance and I never use any contraceptives so the likes are pretty open. But we had that WHOLE week before I came on and everyday the week after i went off. Do you cramp like normal cramps in early pregncy?
