Pregnancy Drama at Work

So I'm 12 week pregnant, and everyone knows it but really didn't congratulate me when I anccounced to everyone. This girl I work with anccounced she was pregnant she 10 weeks and everyone hugged and kisses her. I wished she didn't do it in front of me during my shift. I felt so left out. But then again I been working here for 8 months part time. She been working there for like 10 yrs fulltime. All the time she had when I was on medical leave she decide to tell everyone on my shift when I cane back. My boss loves her too.  She picking out baby names with her. I just feel like very sad. I'm crying.
