Bummed!😏

My period came! After being more than two week late, 6 negative pregnancy tests, and a doctor's visit. I am bummed 😞 Then my sister  in law announces she is pregnant and I am trying not to be jealous. I am happy for her and I am excited to be an Aunt again! But I am little jealous and I don't want to be! Any advice??? 😔😕🙁☹️😞😶😏
