TTC with irregular periods

I haven’t had my period since like March I been trying to conceive for about 3 years now, I’m 20 now, I’ve never had regular periods and I started getting my period very early at the age of 8. But I’m always discharging once a month do you girls think that might be my ovulation? I’m so confused and I want to try everything naturally possible before I go to the doctors and they put me on treatment, 
Any suggestions? On what I should do what ?
