possibly pregnant

so me and my boyfriend have sex basically every day. recently he started finishing in me which i don’t mind because i’m on the pill, and i take it the same time every day. but for about a week i haven’t felt right and i constantly am bloated and feel slight cramping. i have also had multiple dreams that i’m pregnant, and i know that doesn’t mean anything but i have never had dreams like that before. i’m supposed to start my period in about a week but if i don’t, i will definitely take a test and/or go to the doctors. i’m just wondering if any women have been in my same position and if they did end up pregnant? i know it’s possible since the pill isn’t 100% effective
