Five Weeks Late

I have PCOS. My cycles are usually 42-46 days. A few months ago I had a 63 day cycle, but I had just come off of bc so I think it was just my hormones. But usually my cycles are in the 40s. I'm currently on cycle day 74. I took a pg test last week, but it was negative. I'm going to hold out a little while longer before I go to the doctor, but I'm just wanting this to finally be it. We've been trying for 8 months, but my doctor wants to wait a year before I go on Clomid. I'm so frustrated. Some days I want to cry, especially 6 people I know are pregnant by accident and I'm still trying. Ugh.
