Possibly Pregnant?

My period was supposed to start 5 days ago, but for the past 3 days I have been experiencing a little brown spotting as I would normally expect right before my period starts. I have slight cramps and my breasts are tender, but today I believe my sense of taste is off and also I could not stand the smell of bacon this morning for breakfast. I have never been so late with my period but with the spotting and cramps it has me thinking that it will come. What do you think?
