Pregnant??

Hey ladies, i need some opinions. I know I can only confirm pregnancy by testing, which i will do tomorrow. But my brain is everywhere. Me and my SO had sex the day of ovulation, now my periods two days late and i don’t feel af coming ( I️ usually have pretty mad cramps2-3 days before.) I’m very nauseous and my thoughts are everywhere i am not 15 dpo but haven’t tested as I was waiting for af. Any opinions on if you think i am or not. Hope it’s my turn. Any opinions will help call my nerves lol!
