Right ovary pain

I was on the shot depo provera, was supossed to take second shot between july 31 to august 13 but on august 2 I visit my Gyn and we decided to change to combinated pill because of the side effects of the shot, on august 12 I decided not take it anymore because I was feeling extremely nauseas, constipated, bloating, dizziness.

Today I have pain in my right ovary, could it be soon ovulation?
