Unfair

It feels like every time I get on social media I see posts of people getting pregnant with captions like " we weren't trying but so excited " or "best surprise ever" or teens moms at just 16 having unexpected babies and I'm over her try so hard to have a beautiful little baby and it doesn't happen for me! I'm happy for them to have that little blessing but it makes me jealous which in turn makes me feel bad because I know it's not their fault I'm not pregnant yet. Its just frustrating.
