Hey y'all! Okay. So I took two equate pregnancy test yesterday and I had two faint positives both times. So as I was super excited I went to buy two more except this time from clear blue and both came back negative.. I've been TTC for 6 month and I'm really driving myself crazy.. have any of y'all had this happen before? What should I do next? 
Also I'm 2 weeks late for my period
