so nervous

me and my boyfriend had sex at the beginning of my birth control pack on the first week. we used a condom but it slipped off while he was pulling out, he came all over my lower back and there was also some in the condom as well. I missed a pill that week at some point and doubled up as soon as I remembered. i’ve taken my birth control at the same time every day and i’m finally to my period week with no period. i’m so nervous. does it situation sound like i’m fine ? no need to stress myself out
