I know its unlikely, but I think I ovulated early?

My last period was July 26th, it ended the 30th. A had 'dry days' the 31 and 1. But the 2 through the 6 I was very 'wet' and was having cramps like I was going to start my period again but never did. We did the BD the 1, 2, 3, 4, 6, and 8. The past few days I have been having some weird symptoms like headaches, dizziness, more cramping (feels lower than normal) and I know this isn't necessarily a pregnancy symptom, but ear aches as well. It is obviously much too early to test but is it a possibility? Or what may have been causing my cramping right after my period? Thanks!
