Sex on my placebo pill...

Hey ladies I had sex with my boyfriend yesterday and I just realized that I had taken my second placebo pill yesterday and we didn't use a condom.... Would the pill from 2days ago still be affective or am I most likely to get pregnant? Ugh I'm so worried it like totally slipped my mind and I called my boyfriend thus morning and he was like well we will see in 2 weeks don't worry baby
