Could this be implantation bleeding?

Ciara • Mommy to Shellie Grace and Ready to meet Tracyn Wayne💜
So, I last had unprotected sex on the 11th and again on the 12th of this month. My last period started on the first of this month. I am currently experiencing nausea, sore breasts, and fatigue. Today, I started spotting. It was definitely not like period blood, it seemed different and there was very little but it was there. 
Should I take a test or is it too early?
