Am I pregnant or getting my hopes up for nothing?

My boyfriend and I have been trying to conceive for the last two weeks, almost three. Back on 6/11, I started to feel my breasts becoming tender and thought nothing of it. Two days later, for four days, i was spotting. The cramps came and went like usual and for sure ive been getting waves of nausea. But every time I take a pregnancy test, it comes back negative -- yet I have the symptoms. Am I actually pregnant, or getting my hopes up for nothing?
