Should I be worried?

Alison • Just an 18-year-old girl in a relationship. 🌸
So my boyfriend & I were having sex & it started feeling EXTRA good for a minute & then just before he finished, he pulled out & we realized the condom was broken. I saw him finish so I'm pretty sure he didn't cum inside me but he always gets me worried when he's worried (keep in mind he has anxiety so he has very irrational worries a lot). I'm also on the pill & make sure to take it on time every day. Should I be worried that I'm gonna get pregnant? My period is supposed to start in the next day or 2 but I'm impatient & kinda scared. What do you think?
