Delayed Period!

Threw my period off a week last month from stress and now its due today. It hasn't come yet and there is absolutely no way I can be pregnant as I've only been fingered this month (sure there was some precum on his hand, but it is not enough to get me pregnant considering I was only fingered). It hasn't come today, and I was wondering if that is normal, considering I threw my period schedule off last month by a week. I am getting sore breasts, occasional to frequent cramps and some creamy and watery discharge. Should I be expecting it soon?
