Help me please

Samantha

I have been testing with clear blue advanced digital ovulation tests since cycle day 10 like the instructions say. I am now on day 27 and have had flashing smiley (high fertility) for 15 days. Never got my peak solid smiley. I had ewcm 2 different days this cycle and BDed everyday during my window. Can anyone tell me what might be happening. I have an appointment with my obgyn on Monday but I’m so scared of what she will tell me. We have been trying since August 2017 but I’ve been off BC since January of 2017
