Very mild period like cramps during ovulation and pain uncomfortness during sex should I be concerned?

May be normal. Some ladies do get symptoms as you get during ovulation time ,it can be normal and mazy not cause any concern specially when you do not have any discharge or bleeding from vagina .
Mittleschmerz. Some women feel pain at the time of ovulation. This is called mittleschmerz. It is very normal and resolves qucikly. If you feel your pain is lasting longer or might be something else schedule a visit for evaluation.
