To share or not to?

I just recently found out that I am pregnant and have been keeping it a secret from our family members and many of our friends. I have a dear friend who have been TTC for over a year and I wouldn’t want her to be sad if I share the news with her but I’m sure she will be happy for me but you know.. sometimes this kind of friend is just too fragile you don’t wanna hurt her feelings but at the same time you don’t wanna keep it from her either, cause you don’t want her to think that you think she might feel hurt. I don’t know, we are not that close but of all the times, she was there on my solemnization day and allowed me to squeeze her hands. She’s those kind of friend who will be there if you need her though you don’t communicate as frequently. Would you tell her or just keep it a secret until you give birth?
