Could I Be Pregnant?

Hello all,
I am 14 days late. I have never been late before. I have taken 5 HPT but all were negative. The last one I took was at 12 days late. My husband and I were going to start trying after my deployment. I went home at the beginning of May (during ovulation). I am not under any significant stress and I am in good health. I am showing some signs of early pregnancy such as a very light bleed (light pinkish in color), some nausea and vomiting. I just want to know if it is possible to still be pregnant and keep getting a negative on the HPT.
