My friend is getting married and I feel like I can’t talk to her about wanting to get pregnant

My best friend has been engaged for about a year and a half and is getting married in eight months. When she got engaged she asked me to be her bridesmaid and throughout the engagement she asked me if I would be pregnant during her wedding. I didn’t know at the time and wasn’t planning on it, so my responses consisted of “no’s” and “I don’t knows.”

However, my husband and I are ready to try and I’m sooo excited about it. I talked to my friend and told her and I don’t think she is happy. I think she tried to play it off like it didn’t bother her, but I can tell it does. She is a planner and has a hard time letting go of control but the only thing it would change would be my involvement in the bachelorette party pending how pregnant I am and how I physically feel, because it would require traveling via airplane. I told her that I plan on coming and genuinely want to come, but want to be honest about the chance that I’m not able to go. I told the fellow bridesmaids I would still pay for the room for her Bach party and do something special for her if I can’t go. Regardless, my friend isn’t openly expressing frustration with me but I feel it. One of the bridesmaids said she understands why my friend would be upset, which made me feel shitty.

This all makes me very sad because I feel like I can’t talk to my friend about something exciting in my life because I don’t want to make her feel like her time isn’t special. Has anyone experienced his before?
