5th month ttc and still nothing. When is it time for help?

Starting our 5 month of ttc. Hypothyroidism is under control and levels are good for conceiving as per endo, cycles are averaging about 31 days with a 10 day luteal phase as per opks. Used preseed this month and taking prenatal and B6. Thought this month was my month but nope. AF showed it’s ugly face today. I never thought I would have issues as my mother got pregnant right away. I got off of birth control in June.

At this point. When should we start looking for help? I know that most doctors do not want to start fertility treatment until after a year. I can’t imagine having to wait another 7 months of this to get help. Where would we even go to for a semen analysis? I’m wondering if my LP is the issue and if I need to do something to extend it.

Sorry for the long rant. Just upset and frustrated!
