TTC buddy and a dilemma

Claytonia

My friend and her husband started TTC about 5 months before we did. We've stuck together during the whole process for about a year, crying and laughing together. I found out I was pregnant a week ago and she got bad news about her husband's fellas a few days ago. I don't know how to tell her that I am pregnant. I know I shouldn't, but I feel guilty. I know she'll be happy for me, but I really don't want to upset her. She stopped over after her appt the other day, really upset. After venting she asked me how things were going with us and I just said that they were the same. I felt terrible for lying to her, but I just couldn't tell her that we got our BFP when she was so upset.

Has anyone been in this situation? How should I handle it?
