OH SH** FEELING.

🌻Chris🌻
So, my boyfriend and I have been ttc. And yesterday morning, around 5, I got this super nauseated feeling. And then around 5:30 am. I finally had to get up and throw up. I am about a week PO. Could this be an early symptom? Help! 
Could this really be happening? Could it be my rainbow? 
My boobs are sore, and mostly around the nipples. I've been tired, and also getting mild headaches. HELP.
