Pregnant ???

I super doubt I'm pregnant but here's the story: so I started my period Wednesday and left my birth control at home for the weekend (but it was all the sugar pills) had sex on Thursday night on my period and didn't take the pill again until Sunday (which was the next white pill) so the only pills I missed were the sugar pills.... but on Monday I was crying for no reason and today I'm craving hot dogs?? And I don't even like hot dogs?? I can't be pregnant right ??
