The reason most people wait to announce is tied to miscarriage risk. About 10 to 15 percent of confirmed pregnancies end in miscarriage, with the vast majority occurring in the first trimester. However, the risk is not static — it drops rapidly with each passing week, especially after a heartbeat is confirmed.
A dating ultrasound around weeks 6 to 8 can confirm a heartbeat, which significantly reduces the statistical risk. By the time you reach 12 weeks, the chance of miscarriage is about 1 to 2 percent. Understanding these numbers can help you choose a timeline that balances your desire to share with your comfort level regarding risk.
It is also worth noting that chemical pregnancies — very early losses before week 5 — account for a significant portion of the overall miscarriage statistic. If you are past week 6 with a confirmed heartbeat, your individual risk is already much lower than the headline numbers suggest.
