Pregnancy announcement on social media. When did you announce your pregnancy? And why?

My husband posted it when we got the first TVS ultrasound. I told him to post once d fetus has a heartbeat na po. wala naman pong stress na nganap after announcing it... everybody was happy and celebrated with us. btw,we waited for 4 years.. it was truly a miracle baby for us despite the medical conditions that we both have as a couple po. 😇🥰
