Ovulation

The parhams • TTC Baby #1
I have been trying to get pregnant for over 6 months with no success. However I've only been bbt charting for 2 cycles and using opks during my current cycle. I've never had regular periods. Maybe once in a while but not very often. I have a normal 5-6 day period. Should I see the doctor or am I just impatient? Advice?
