Possible pregnancy???

We'll me and my friend had been having sex like crazy for the past two weeks and now I'm having slight pain in my stomach and very sleepy and cranky all the time and the crankiness was always a sign of pregnancy that's how I found out about my other pregnancies, but it's soon to tell. My period is supposed to start on the 10th of this month, but I was uncertain if taking a test was necessary. I'm labeling him my friend because we're in a relationship, but we're not just to clear up the friend word lol, but I wonder should I take a test because I'm excited and scared at the same time!!! Any suggestions???
