I'm really struggling to understand why I'm not getting pregnant after trying for the last 6 months. I've already got a 6-year-old son and was told I have PCOS. Since December 2015, my periods have been delayed by 2 to 3 months, and even though all my test reports came back normal, I haven't been able to conceive. Last cycle, I did follicular monitoring, and my egg ruptured, but I'm still not having any success. What else could be going on, and what should I try next?
