7dpo symptoms?

Marissa
My SO says my nipples look "puffier" and I've been feeling SO tired I'm like barely able to keep my eyes open past 6 pm and I've had no appetite and I feel not like I'm gonna puke or nauseas but my stomach is definitely feeling sensitive and queasy. PMS or pregnancy? Anyone else due the 3rd? I'm going crazy 😭😭😭
