Possibly pregnant?

It's too early to test, but Hoping for some positive reassurance: )

I am pretty sure I ovulated on the 2nd due to my CM. It was very stretchy and almost tanish in color. My husband and I BD on the 1st, the 2nd and 2 days after ovulation. Since the 3rd I have been having cramps on and off. And I'm pretty sure it's not my period, as I ovulated early this month. ( finished AF on the 27th. Was 5 days long. ) I haven't had any implantation bleeding though. Could this be a good sign though?
