Possible implantation cramping?

So I'm 11 days past ovulation. Last yesterday around 8pm I started cramping and don't usually cramp in the middle of my cycle unless I'm ovulating. Today I feel like crap. Having hot flashes and been very tired and lazy. Could it have been implantation? I haven't had any spotting. TTC for #1, month 3
