I’m so confused !!

Hey ladies,

So I’m really confused!! I was supposed to get my period last Saturday, it never came. I thought “ok we haven’t been trying I could be pregnant” so I went and bought some tests and all have been negative. We are going on a week and no period still. I have not even felt like it was going to start, no cramps,nothing what so ever.

This has never happened to me ever, I have considered stress but even at my worst & dealing with stress I have always gotten my period.

Has this happened to anyone else and or do you all have any suggestions or opionions??
