Am I Pregnant? What do you think?

Me and my fiancee had sex mostly everyday when i was ovulating and since then I have been getting cramps, needing to go to the bathroom more, Headaches, Nausea and dull ache in the lower back. I was due on my period on 6th June which was late and the about 3days after the 6th I got a brown discharge with a few light pink spots in it too which lasted 3days. Today my nipples are so tender to touch to the slightest squeeze or touch and my fiancee said they looked redder than normal. These last few days I cannot control my emotions I have cried for no reason and been aggresive for the stupidist things. If i am pregnant i would be around 6weeks, I am going to do a test later on today but can anyone tell me what they think. Thanks :)
