First time ttc... I want to know more!

Monique
This is my first time ttc for our first baby. Af is due Sunday the 28th, hoping it doesn't, I've been nauseous on and off, so tired, my nipples have been sooo sore.. only when I'm not wearing a bra.. I almost cried the other morning it feels link someone's pinching them super hard. I've been having some cramps here and there. I'm at 12 dpo. I want to know if these are normal symptoms, what are some other early symptoms? I just started getting these about a week and a half after I was ovulating.
