Am I A Bad Person

So last week, I found out my best friend was pregnant and I'm happy for her honest, we've been friends a long time all through our childhood and high school years. My husband and I have been trying for over a year now and nothing has happened and all of a sudden my best friend calls me up with the news that she's pregnant no problem, she'd told me two weeks prior that she was going to try because it was her fertile week. And surely enough she sent me a pic of her test to confirm and there it was a BFP. Two thick, dark lines. I'm so frustrated, angry and emotionally distressed. Am I the only who feels like everyone around you is getting pregnant and starting the next chapter while I'm just stuck wishing. I mean every time my AF is late I think I'm pregnant and then it starts. Not only do I have to worry about the possibility of not being pregnant every month, but I can't pin point my ovulation or tell if I'm ovulating at all considering I don't menstruate regularly. I'm starting to think I'm incapable of having children at this point. Am I wrong or a bad person for feeling a little jealous if my best friend after all we've been through?
