Early Symptoms?

I'm 20, TTC. My partner and I have had sex throughout ovulation window. Only 2dpo, but I've got very sore nipples, I get nauseous if I smell anything with a strong scent, I'm urinating a lot more than I usually do and my stomach feels very fragile, like I can't touch it...sometimes when my partner and I cuddle, he lays his head on my tummy but I can't stand it, I either feel like I'm going to puke or like he's squishing me and it gets very uncomfortable.
