Pregnancy symptoms or pms ?

Scared i might be pregnant. I’ve been trynna be safe but I’m nervous we might have slipped up. We’ve had sex 3-4 during my fertile window using the pullout method...Body has totally been feeling weird my boobs feel insanely heavy and my nipples are so sore and tender. Can’t even wear a bra they feel so sensitive. My boobs never feel any type of way around my period so this is kinda weird and I’ve been super nauseous but no vomiting just feeling like I have too throw up. my mouth is super watery. I’ve been cramping slightly but I never cramp more than the day before my period starts. My period is supposed to come in 6 days. What y’all think ?
