Why not me, too?

I know it isn’t just me but lately I’ve been really upset that I’m not pregnant yet.. we have only been trying for a few months and I know it takes time but it just really hit me this past week, yaknow? I see all the people letting their families know that they’re pregnant, finding out the babies gender, and having their babies and I’m sooooo incredibly happy for them but at the same time I’m sad.. like there are girls who have to try for years and never end up pregnant and then there are other girls who don’t even try and bam they’re having a baby. I know I shouldn’t be but I’m so jealous and just overall sad.. :(
