Woman 30y.o.is it normal to feel ovulation pain on both sides some months?normal it is more on one side but sometimes it is on both ?

It is possible for both ovaries to release an egg each in a given cycle.

Not uncommon is the simultaneous maturation of two follicles , sometimes one sided and/or on opposite sides. This would not be a frequent occurrence. Pain on both sides could also be caused by pelvic infection. See your GYN physician for an exam and further testing (ultrasound and/or culture).
