First month ttc

I can’t help but be really nervous and anxious. My period is due in 5 days and I just really want to be pregnant. I usually wake up nauseous so I can’t use that as a symptom but my nipples look different to me. the bumps on them look white and red and smaller than usual and my nipples are darker and one has gotten bigger. I feel like i’m putting this stuff in my head bc I want to be pregnant but it also feels like I am, idk I don’t want to get my hopes up.
