Period symptoms or pregnancy symptoms?

Hi, I lost my virginity two and a half weeks ago, and we used a condom and he pulled out. However, I was supposed to get my period two days ago, and it hasn't come yet. I am experiencing tenderness in my breasts, breaking out on my face, and I got strangely emotional today for a small reason. I also got very bloated today. And the discharge that naturally comes from down there is a lot and it is faintly yellow-ish in color. Does this mean I am getting my period soon? Or are these pregnancy symptoms? Please help, I am very scared. How accurate is a pregnancy test at this point?
