So confused.. advice please!!

Melissa

My husband and I have been ttc for 2 plus years and have had no luck. I was due on November 21st for my cycle and I have still yet to receive it! I have done 4 HPTs all faintly positive. I recently had two blood test one last week and one this week (quantitive & qualitative) and they were both negative!! My doctor is going to examine me on Thursday (1/10/19) and then order an ultrasound just to ensure I am not in fact pregnant. I have never missed a period except for the both times I was pregnant with my children. I currently have two children now and found out super early with both. Has this ever happened to anyone? Even though the hpts are positive and the blood test are negative.. could there still be a chance??
