I have taken 6 tests this month and they all have been coming out negative. I have tried clear blue,first response, and a walgreens brand all with 2 tests each. I am 2 weeks and almost 3 days late. WHY AM I STILL GETTING Negative?? I was told maybe it is because I have a really low level of hcg in my urine. Do I have to have a pregnancy blood test done to tell me whether I am pregnant or not? Also what happens if that come sout negative too is pregnancy still possible? I am not stressing out I'm just confused on this.
