plan b anxiety?

my boyfriend and i had sex and after we were finished we realized the condom had broke and he came in me. we immediately started searching for drug stores that were open 24 hours. i ended up taking a plan b about 2-3 hours after it happened. i’m having a little bit of anxiety about whether or not it will work and i’m just looking for advice on if i’ll be in the clear?

also i’m not sure if it matters but i want to mention that i had drank a little bit but not enough to get drunk. i had two truly lemonades so really not much at all. i’m not really sure how this all works so i just wanna give all the information

my boobs have also been sore randomly and i’ve been getting cramps every now and then. my next period isn’t until the 10th but this all occurred about 2-3 days before my ovulation days (according to the app)
