No AF but BFN

lekha

My LMP was on january 8th.I have taken clomid day2-6, Then from 9th day follicle scan started and Gonal F injection was given as follicle was not growing. Till Day17 this happened and follicle didn't grow. So we stopped monitoring this cycle . Today is Day36 and no AF. I used to get AF normally befor day33. HPT done and it is BFN. What is happening with my body? Any insights? So confused
