Unprotected Sex

Obviously when you have unprotected sex there is a risk, but i’ve been on the combination pill for a year now and i can’t remember the last time i’ve missed a pill just because it’s been so long since i have. and my boyfriend and i had unprotected sex, and usually he pulls out, but this time i think he came in me as he was pulling out. he said he pulled out all the way and then he came, obviously stupid of me, but am i protected i take the pill everyday around the same time. i just didn’t know if i should go get plan b, or i didn’t know if i’m wasting my money and putting a shit ton of hormones in my body wasnt healthy. this hasn’t happened to me and i don’t want it to be too late. tell me what you ladies think!
