Can this have been Ovulation cramping?

Yes for sure they could have been ovulation cramps. If you period is not a 28 day cycle then you would ovulate later then day 14. So that would have been day 11 to 16 depending on when your period comes this time. Remember that if you are later then 28 days then yes you would definably ovulate later then day 14. So hopefully you and your hubby did it on the days you were cramping just in case it was ovulation. I will keep my fingers crossed for you.
