Could I be pregnant?

I have had a few symptoms appear that have made me think I could be pregnant but I've not got my hopes up, I still have 6 more days till my period. Just in the last week I've had change in my bowel movements, 
Breasts have been so sore I couldn't wear a bra, the smell of milk makes me sick-I normally LOVE milk, I've been having crazy dreams, and I'm spotting. -I have only spotted before my period a hand full of times.  
Could anyone give me some advice? I don't want to tell anyone because I don't want to make it a big deal if it is not. 
I know only time will tell, buuutttt a girl is curious.
