To tell or not tell? What would you say?

Aimee
One of my friends knows I was TTC, then found out I had PCOS and was seeing an RE. I'm currently 11 weeks but only some family members know. I was planning on announcing to everyone else after the 1st trimester is over (another 2 weeks).....she randomly messaged me this am wanting to know how things were going.....I kinda want to tell bc I'm excited, but at the same time I don't want to yet and just wait....but I would feel kind of bad lying.....what would you girls say?
