Should I discontinue the tablets in the case of migraine with aura? Can you change them to single-component?

Hello, for two months I take birth control pills Activia Daily. In the last week, before the withdrawal bleeding, I experienced temporary, but quite severe dizziness. It's never happened to me before. I thought it was probably the fault of the tablets and learned that two-component tablets must not be taken for migraine with aura. Two years ago, your neurologist said that I didn't have one (I also had a head resonance). The fact is that I have had the migraine aura itself for several years (I am currently 23 years old, and the aura has been around for 6 years), but it never heralds a headache - I see only for about 20 minutes the darkness, flashes, increasing light half-moons. Should I put off the tablets in this situation? Can you change them to single-component? I am very interested in hormonal contraception In addition, I will add that I have a heart defect, which is moderate aortic stenosis, biplane valve. Please advice.
