Firstly congratulations.
Personally, I suffered with secondary infertility for a very long time. Every time I got pregnant over 6/7 years I told those close to me early. From about 6 weeks, because I wanted them to understand if I went under the radar why.
I have a couple of close friends who were in the same situation and others who got pregnant successfully after a cycle or two.
I never once begrudged or was jealous of someone else's news or babies. Every woman has her own personal story and relationship with fertily/infertility including those who are childless by choice. I've always respected that.
I would get minorly upset if someone assumed because I had issues, I wouldn't be happy for them.
I shared my news and preferred others to share theirs as they saw fit and did what suited them and their circumstances best.
I wouldn't overthink it. When you're ready, share your news how best suits you. Your pregnancy is yours. No one else's. I think we often over pander and worry about other people and being 'sensitive', when we shouldn't. It would upset me when people would say things to me like...." Oh, it must be so hard for you knowing suzy is having another baby, she should have told you one on one or text you text to give you the heads up" No, Suzy shouldn't have. She did the right thing by celebrating her news as suited her and I wished her all the best because as a friend, I care about her happiness and well-being.
Enjoy pregnancy, if you lose friends along the way because they can't be happy for you, you're better off without them.
