announcing pregnancy

My husband and I tried for three years and went through over a year of treatments and endless doctor appointments and by a miracle are pregnant. I have a friend who is still struggling 10 years later. I know there are others out there who are struggling also and I want to be conscious of their feelings when I announce we are pregnant. We told no one as we struggled and told no one how painful it was when they announced. The point is does anyone have any tips on how they announced to be more conscious or any advice. Thanks!!
