TTC after nearly 15 years on BC 😢 anyone else this long?

I have been TTC for nearly 6 months now but I have been on several contraceptives for nearly 15 years, from the pill to the injection then for the last 4 years the implant. Anyone has any comments on how long they were TTC after contraceptives. My period started straight away and my cycles are back to normal immediately after implant removal. I took an ovulation tests last cycle and for 2 days out of 4 testing came back that I was ovulating but BFN. 
Baby dust to everyone!
