Fertile week but no LH detected?

Lizzie • Starting over. Done with assholes and false promises.
According to glow and several other apps I should be in day 2 of my fertile week. I've been using OPKs and haven't had any LH detected on my test. Is it possible I'm not really in my fertile week? Or something? Normally I get faint lines that get darker but so far nothing. Is it possible I won't ovulate this month? I do have PCOS but have finally been regular and thought this might actually be my month
