First pregnancy symptoms

My boyfriend and I had sex about a month ago on the day I was ovulating. He of course pulled a goalie, or however you would like to say that. And I've been pretty nervous because my period still hasn't came. I'm 5 days late, my boobs hurt and my nipples itch like crazy. It feels like I'm cramping sometimes but nothing has came. I kid of wanted to get some insight on if I should go get a test our if it's too early? I'm hoping I am pregnant, we gave been trying for some time now. What were your first symptoms? It got a test to see for yourself?
