Can I still get pregnant while late

Amber

My period is 11 days late I’m trc first month iv went through about 15 gets all negative so am I out ? I hear people say your not out till period shows up but I don’t think I’m pregnant I’m just late cuz I have a 37 day cycle irregular sometimes. So have I just not ovulated yet? Can I still get pregnant right now ? I really need help! Do I have to wait to try again until my period shows up ? I get pregnancy symptoms I have constant twinges and my head has been hurting for the past week but no Af symptoms at all
