CD 83, 40 days late, bfn

Hi you all,

I wonder if any of are in the same situation...

I came off the pill about 8 months ago, had normal cycles for a while now it has been 83 days since my last period. I chart my temperature and opk and I had confirmation that I ovulated about 55 days ago but since then I have had no symptoms and bfn all around. I have had a blood test to check for thyroid issues and there was nothing there but my doctor refuses to investigate further because we have been tcc for less than a year. I wonder if any of you have ever been in this situation and what happened in the end. I don’t know what to do...

I appreciate to it feedback

Thank you
