Implantation Cramping or something else?

Ok at first I thought I had already ovulated(positive ovulation test) but I found out the day before yesterday that I was just ovulating because I started having that egg white Discharge and my husband was also able to tell :). So anyway I have been having cramping all day and I feel it more on the left side can it be to early for it to be implantation cramping. My lmp was May 28 so its still to early for my period. Please help
