Bad at birth control

So I'm horrible with my birth control pills. This month there were quite a few times where I would miss a day and then have to take two. There was even a time where I missed two days so ended up taking two pills one day two pills the next. I know, not safe. Would it still be effective taking it like this or would it basically do nothing? I had unprotected sex this weekend, and he pulled out, but glow says the day it happened was during my peak fertile window. Is there reason to worry? Or should I be good?
