Will pregnancy protection be maintained?

Was the protection against pregnancy preserved if I ate flakes with milk in which there were oatmeal some dried fruits but there was also flaxseed. Then I took a vibin mini tablet. I have no idea but there were grains of flaxseed. In the list of ingredients in the whole 400g package there was 5% flaxseed at the same time not know how much I could eat it. Should I take a duga tablet in addition to the one I took. And does the fact that I lived the day before mean that the protection will not be maintained
