Ttc and X-rays

I'm currently 4dpo and am due to have a mouth X-ray done tomorrow. I worried that it might ruin my chances for this month and want to tell people about my situation but don't know how with out getting that look ( u know that look as if to say " I'm overreacting and am thinking way to much into ) 
Should I just bite the bullet and speak up or is it way to early to bother what could possibly be ?
