8dpo....HELP!

Lindsey • Christian, Married, Mommy of 2 boys, step mommy of a little girl :) TTC our rainbow baby :)
I've been TTC forever now...I'm currently 8dpo and vomited 3 times this morning, I still feel queasy but haven't thrown up again yet today...I also have extremely tender sore breast... 
   For all the previous cycle Ive never thrown up or even felt sick...I had a chemical in January last year even then I didn't get sick nor with my two boys ... Could this mean I nailed it this month ??? Anyone else have symptoms like this early on!?
