New to glow.. Trying to conceive but no luck

I honestly feel like I'm making myself go insane. To the point where I feel so emotional it's like everyone I know is getting pregnant except for me. Just a few weeks ago my husbands sister found out she was pregnant & I'm so sad & bitter. It's ridiculous.. He wants a baby just as bad but he's more calmed about it. We tried on the 17th since it said that's when I had the 33% chance. & we tried the next few days. . . I really hope it happens.
