Pregnancy Failure - again.

Let me preface this with a couple things:

1. I know we haven't been trying that long compared to others. But we are both so ready to start our family.

2. I was diagnosed with PCOS so my periods are super irregular. I'm not currently on any medications, but will be getting on Metformin soon.

I'm on cycle day 50. I started ovulating CD38 (first time ovulating in 3 years!). I woke up this morning excited to test because I haven't had any normal period symptoms and have had a few pregnancy symptoms. ANOTHER BFN!!!!

I'm just so frustrated and I'm at my wits end and all I have ever wanted is to be a mom. I've been praying earnestly and constantly for this to be it, begging and pleading and I just don't know what to do anymore. I just don't get it. How are there so many awful, terrible people out there who get the opportunity to have children and abuse it, abuse their children, and yet it's "not my time"? In this awful world where parents murder their own children or sell them into sex slavery, I am below them on the list of people who's time to fall pregnant has come??? I just... I don't know what to do. I guess I'll just keep praying and waiting for now, but it's all I can do to keep from screaming at the world and lying in bed all day sobbing because my body has betrayed me once again.
