Can anyone help? Cycle day 44!

Hi Everyone. Me and my partner have been trying for around 11 months now. My periods have been the same every month now for those 11 months. It’s always a 37 day cycle. However, I am now day 44, and have still not got AF, or a BFP. I’ve got pictures of tests I’ve done since 11dpo, and although I thought I saw a faint positive in the first picture, I keep getting negatives. Has anyone had this before? It seems as if I’ve completely missed a period, and still not had AF
