Is it possible? Need help..

We are currently TTC our first.  I got my last period on October 6, so I didn't take a pregnancy test..(Because I got my period)  But now my body is being weird.  I puked yesterday morning, my body has been sore, my breast are sentative, and I think I have been smelling a lot more which somethings have turned my stomach.. At first I thought I was sick, but it's all the wrong symptoms, so I was thinking It might be that I'm pregnant. But Is it possible I could be pregnant? Even though I got my period? When should I take a pregnancy test?
