Cramping?!?

Nesa
Hello ladies,
I am currently in my dreaded TWW, approximately 2 dpo, if I did the calculation correct. I have been experiencing some cramping today, no bleeding. But definitely some cramping, not one sided. More general. I know its not late ovulation, got positive OPK Sunday and a rise in bbt today... Any thoughts or did this happen to any of you ? TIA any advice would help!!
