I think im overthinking this lol

I just started taking bc pills. Me and my fiance had sex without protection and no withdrawal on the 5th and 6th day i started taking them. But that was it. And now im on the 3rd placebo and still no period. And I don't even feel like im about to get it like I usually do before the pills. I'd get cramps a day before or just a feeling that its about to come... 🤔🤔🤔🤔 where's aunt flow. I kinda miss her
