Assisted Fertility Advice

Spacey
Question for you ladies that have done or are going to do IUI or IVF. How many months were you TTC before you decided to do assisted fertility? And how did you know that was the path you needed to take?
Background- Husband and I have been TTC for 2 1/2 years. Diagnosed male fertility issues (low count and low motility) husband has been on Meds for sperm quality for 1 year. Trying to get pregnant every month only to get AF each month is heartbreaking and exhausting. 
Just looking for advice or words of wisdom. 
Thanks 🖖🏼
