All these symptoms mean pregnancy.?

Lately I have been experiencing headaches, fatigue, moodiness, i have been sick in the mornings and evenings. My last "period" was very very very light and i didnt pass any clots and it was brown blood the whole time. I am not due for another week or two and dont usually get sore tender boobs until a couple days before. And now my boobs are very sore. My period is never irregular soo i believe im pregnant does this sound like my symptoms are pregnancy related??
