Pregnancy symptoms

I've been experiencing spotting, which has now stopped. I'm always tired and I have an appetite which Isn't normal because I don't rarely eat. This morning and now I have been feeling sick but not being sick and a a burning feeling in my throat. I have also got a few shooting pains in my stomach. My body feels strange compared to normal. I was on my period on the 6/11/15-10/11/15. I was late on as I'm always due on the end of the month sometimes a week before. Do you think I should take a test, my pregnant friend thinks I should ?
