Could this be Implantation cramping?

I am supposed to be ovulation from 8/25 to 8/30 and I have some slight cramping each day, it is on and off. Hubby and i have bd every other day since 8/21, I really hope this is my month....any opinions or advice. We have been doing the pillow under bum and ive stood on my head....I also get a sort of a bubbly feeling in my abdomen could be gas tho. I have had some recent preggo dream (lol) and also I pee a fricken lot....i know that its too early for that to be a sign but hey has anyone experienced this beside me....? Maybe im just crazy...lol
