In a word: no. Not yet, anyway. If you're sure of when you ovulated, then you most likely wouldn't be experiencing pregnancy symptoms yet. That's because if a sperm does fertilize your egg during ovulation, it still takes seven to twelve days after that for the fertilized egg to implant in the wall of your uterus. Once that happens then your body starts responding to the pregnancy.
All of that being said, I do believe that there are women who experience symptoms right away after fertilization. However, it's debated by medical professionals.
It's most likely that the cramps you're experiencing are post ovulation cramps - a normal response to ovulation.
In six days, at ten DPO, you should be able to start testing for pregnancy with a fair amount of accuracy.
