Pregnancy symptoms?

Paige

I am 12 dpo and I have swollen br__sts but not tender or sore at all? I've been really nauseous and tired and not having much luck going to sleep. This is the first month we've been ttc after and I feel like I don't know my body anymore. I started cramping today but not bad like my normal pms. I'm testing in the morning but my mind can't stop racing, could this be pregnancy symptoms?
