Feel sad.

I know I should feel happy but I'm feeling sad. Me and two girlfriends decided to start trying to get pregnant at the same time. I started six months ago however and for different reasons they didn't start right away. One friend started in July and the other August. They are now both pregnant. Four weeks and six weeks. And I'm not. I'm happy for them of course but also I feel sad and broken. Have an appointment with my midwife on October 15 to talk about clomid or something :(
