Faint line than negatives

Heather

I am so confused... I was due for my period yesterday and no signs of it coming. 2 days ago I took a pregnancy test with a faint line of positive. I have been urinating constantly, hot flashes and shortness of breath and nipples have been erect for a few days. Today i took a test hoping for a darker clearer line and 2 different kinds today both say negative?? I was soooooo excited and now i am confused??
