anyone else experience this in early pregnancy?

I have been TTC for 6 months, and AF is due in 6 days. I know it's super early to have any symptoms, but the last few days I have had a few things happen and wanted to know if I was alone or if they have happened to anyone who has been pregnant before. :) 
About 7-8 DPO I was getting ready and all of a sudden got very naseous and threw up. I felt better immediately afterwards. Then, the next few days after that my boobs started to get very sensitive. Also, I have been feeling like my heart has been skipping a beat every 5-10 minutes. 
Anyone else experience any of this? Hoping for a BFP soon. Fingers crossed for me!
