Wishful thinking

So I've had normal cycles the last few months and my period always comes on time. Well I'm having the same symptoms i usually do right before af shows up but it's not due til 15th. Could these be signs? I could have ovulated early or gotten pregnant on a day that says like 8 percent chance I'm not sure. But i absolutely hate the cramps and feeling i get before af. I definitely don't want this for 2 weeks.
