Have this happen to you?

OK I am 5 days late and haven't taken a pregnancy test. I have no signs that my period is coming. But I did have a brown discharge the day I was suppose to have my period with a little bit of cramping and that was it. Now for the pass three days I have been crying over the littest things. Like I had some floating in my drink and I cried like it was the end for me. I have sore breast, bloated, extra sensitive extra tired, and eating a lot. Have this happen to anyone and it turned out you was pregnant?
