Need to vent

A lady I know has to use <a href="https://glowing.com/glow-fertility-program">fertility treatment</a> to get pregnant. She has a 2 year old and 9 month old twins. She has been doing fertility treatments again and just found out she is pregnant yet again but is "disappointed that it is only one baby this time" I'm not happy for her. That might make me sound like a horrible person but I'm just not. I've been trying for almost 2 years and she has the nerve to tell me she's disappointed she is pregnant with only ONE!? And not only that but it's like she's trying to see how fast she can pump them out. Call me jealous I don't care. I just feel like she is being extremely selfish about the whole thing and taking for granted the fact she can even get pregnant. 
Sorry, rant over.
