Should I be concerned?

I was having sex with my boyfriend monday night and we were using condoms, I was on my 6th day of birth control (after my placebo pills and period) and I usually have him pull out when he cums because condoms have ripped before while we use them and I like playing it safe. Lo and behold he is about to cum, pulls out and the condom stuck inside of me. I didn’t know how much cum was in the condom and we rushed to Walmart to buy the plan b one step generic brand. I took it within 25 minutes of have sex.

What do y’all think? Should I be concerned?
