2 weeks late but still a BFN

Help! My husband and I are TTC for the first time. We have been trying since May and had 1 miscarriage in July (very early into pregnancy). I am currently 2 weeks late, but still getting a negative. Also, it's probably important to note that last month I started my period 4 days late. I'm hoping there's still a possibility of being pregnant. Does anyone know if it's possible to have negative hpt, but still be pregnant? I'm trying not to get my hopes up... 😕
