help please

Hi I went to help with my dd's swimming class and so missed lunch when I came home I was really hungry so I had two of the ryvita pumpkin seeded ones with two table spoons cottage cheese and my test just now is 8.7 ..surely ryvita are not that bad or was it my coffee (no sugar) or the cottage cheese ..have to say I'm very shocked

Thank you both no I didn't check before I ate I had breakfast at 8 and then was out till 3 so I was simply hungry..will be more careful..didn't know that body gave dumped sugar into bloodstream have just had to read it up.will do all I can to not miss lunch again ;-o
