Contraception Pill transition

Hi

So I changed from mini pill to yasmin combined pill with no breakthrough bleeding. Is this normal?

I asked a doctor at an std clinic and she said it depends on ur body but not sure.

Oh and on the yasmin pill ive had intense nausea and enhanced urination as well as ovary/right side pain. Is this normal?

I think I'll come off the pill because its so unbearable. Anyway thanks in advance for answers!!
