might not be the cause of the swelling you complain of.
And ovaries cannot be palpable, especially when they are small.
I feel the swelling you complain of is most probably a hernia- given the nature of popping up, easy reducibility.
wouldnt have picked up anything because Hernia reduces on lying down.
You continue taking Balzivia if you need contraception
Consult a Surgeon early as you have started developing pain in the swelling.
All the Best.
