Feeling down

Hey moms I’m currently 6dpo and I start my period in 9 days. I’m hoping that I’m pregnant but for some odd reason I don’t feel like it’s gonna be my month. My partner thinks I’m pregnant and this will be his first child, my second! Idk I’m afraid that I’m not pregnant this isn’t my month and Ik that’s gonna hurt my partner but I’ve been talking to him about it like“what if I’m not” and he always says you are, or will be! It hurts my feelings
