What should I do ??? Plan b

Hey I’m 18

I just had sex with my ex boyfriends and I told him not to cum in me because I have not been consistent with my birth control pill. We had sex and what I thought I saw he pulled out.TMI (i felt it in my butt ) But then later he txted me after saying u better “take that pill”.

But here come the confusing part I been taking my birth control pills EVERYDAY but NOT at the SAME TIME. For example

One day I’ll take one at 8pm and other at 2am another at 10pm another at 3am etc BUT I missed one day but then doubled when I noticed I missed a day.

BUT I always end up taking my pill so my question is do I need PLAN B or no!! 🔥🤦🏾‍♀️🤦🏾‍♀️🤦🏾‍♀️
