Am I Pregnant?

I have been been having nausea, extremely sensitive breasts and cramping for the past 4 days. I had my monthly cycle from July 2nd - 6th. We had intercourse on the 7th, 8th, 10th, 12th, 13th, 14th, 15th, 16th and 17th sometimes more then once. If I conceived on the 7th that would put me at 2 weeks and 2 days which is the same time I found out I was pregnant with my daughter. My period isn't do another 9 days.... should I take a pregnancy test or wait???? Help!!!!!!!
