Guilty for announcing..😔

I am currently 12 weeks and have a job where I am often on the road or working from home. My husband and I tried for this baby for a little over a year. Because I don’t see my co workers often in person, I wrote an email to announce I am expecting. While on a conference call the following day, one of my coworkers said “congratulations this will be our first baby for this team. Hopefully we have another because you know that (other girl I work with) has been trying to get pregnant.” I explained to her that I felt horrible announcing because I knew that but figured I had to let them know. I also said if the tables were turned I would be very happy for her too. I just feel the comment was unnecessary and just made me feel terrible. Am I being hormonal??
