Not sure if I could be pregnant?

I know it is too soon to take a pregnancy test so I'm looking for some opinions!  My hubs and I had sex on 5/1 when I was ovulating.  Since then I have felt a dull cramp/ache sort of like AF cramps except AF is not due for another 8-9 days.  I have an extremely regular cycle, so I know I'm not going to start my period this week.  Opinions???  Thanks!!!
