BFN..broken😭😭😭.!!! Period due tomorrow...

Hi ladies,

My period is due tomorrow( march 2nd). So when going through many BFP posts here I thought why not take a test and took a digital test hoping it would come positive. But as usual it came out negative and i am devastated and crying. How sure can I be through these tests. I am honestly losing my hopes every passing month. I badly want to be pregnant...
