missed pills, should i be worried?

so i’ve been on birth control for a few months now. my period ended a few days ago and i was supposed to start my new pack of pills on sunday night, but i forgot. i took it the following morning. that night i had sex without a condom but he did pull out, and then forgot to take my pill that night as well. i took it the following morning again (today)

i know i’m stupid 🤦🏼‍♀️ just wondering if i should go get plan b or not.
