Hard to stay positive sometimes

It's so difficult to stay positive when my DH and I have been trying so hard for baby #1, but keep getting BFNs and seeing AF month after month. Three of my coworkers are pregnant. THREE! I'm over the moon happy for them, and I try to hide how sad and jealous I feel because I don't want them to feel bad for being pregnant - they SHOULD be happy. I don't want to take that away from them at all. It seems extra hard, though, when they complain about being pregnant. I try to be supportive, and I know they're not being insensitive on purpose, but I'd give just about anything to be in their situation right now. 
​Okay, pity party over.
