Missed period am I pregnant?

We are trying for a baby. I've had my IUD out since September tried and tried and nothing. I'm now 11 days late on my period I took a HPT first few days after my missed period and negative result. I have taken another one since on the 9th day missed but still showing up as negative? Anyone have any advise for me? I'm trying to stay positive but we want this so bad 😫
