Expected AF day 3, cycle day 38...no AF

Amy • Married to the love of my life and TTC#1!
Hi all, today is the third day in of my expected AF. My cycles have always run as predicted and fluctuate between 34-35 days. Generally about a week before AF I experience all those lovely aches, pains, and moods that indicate an impending period. This time I have had none. My CM is creamy and abundant. I have taken two HPT, one on day 36 and another today, day 38. Both came out BFN. How upsetting :( confused as to what is going on and wondering if there is still a change I may be pregnant? Any insight from you ladies would be greatly appreciated! Baby dust!
