Lutheale phase defect?

Emilie
Hi, my lutheale phase is usually 12 days max. Today is 10 dpo and I started spotting very lightly so my period should be here tomorrow morning. My period is really short lately, 2-3 days max and very light. Also ovulation is damn painful. It makes my hip hurt badly. Do you think I could have that? I am worried that I won't get pregnant. I am nearly 30 and we already tried six months with opks and basal body temperature tracking. And I read that like that you should usually get to pregnant within six months or go see a doctor.
