Ovary pain

A

This cycle I quite BC and I used CB ovulation test to see if I will ovulate and I did get the happy(peak) face, but I noticed both my ovaries hurt a bit. Isn't that every month one ovary only produce an egg? Is this normal? We did have sex(unprotected) on the peak day so is the pain because of it?

Sorry for the weird questions this is my first time taking a BC.
