Wtf....

I'm testing over and over and over. And I'll I get is BFN
But recently I've been SOOO nauseous, to the point I have to close my eyes and take a deep breath to prevent vomiting. 
I'm 10dpo, idk if
I'm to early or what, but this month was the month that I was almost positive I would get my BFP.
I feel horrible, my boons are sore. (Not to the touch, but heavy feeling and sore) 
UGH what is happening to me if I'm not pregnant. 😭😔
