How to handle pregnancy announcements from friends

How does everyone handle pregnancy announcements from friends while your struggling with ttc??? Recently, an extremely good friend (how also happens to be my neighbor) announced she was pregnant...she knows we are ttc, so she waited until the moment she put it on social media to tell me. She wanted to announce it to FB so bad that she called me at work bc she didn't want me to see it on FB before she told me. Problem is all of our mutual friends already knew but she was worried to tell me. I told her I was extremely happy for her, and I am...of course there is a side of jealous inside but remained so happy for her. Since then she has stopped talking to me, deleted me off all social media sites, and when I see her outside she puts her head down. I don't know what I did to upset her, but I feel overly hurt that she knows my DH and I are having issues ttc and she just shut me out....so my question is did I do something wrong or not act excited enough for her pregnancy??? I am worried to confront her but at the same time I don't need the added stress and maybe the toxic friendship?! Thanks end rant!
