There is no single right answer: waiting until 12 weeks and telling right away both have real arguments. The approach the book describes as the most common among well-informed women is to tell in layers: your partner and one or two very close people on the day of the positive, close family after the first ultrasound (weeks 6 to 8), and everyone else after 12 weeks.
The classic argument for waiting: the risk of miscarriage drops significantly after 12 weeks, from about 10 to 15% in the first trimester to less than 2% in the second. Telling earlier means that, if there is a loss, more people will need to know. It is a real argument, but it has a cost: if the loss happens, you may live through the grief alone, or only with your partner, without a wider support network.
The arguments for telling before 12 weeks:
| Layer | When | Who |
|---|---|---|
| Layer 1 | Immediately, the day of the positive | Your partner; maybe 1 or 2 extremely close people (a sister, your best friend, your mother); your doctor |
| Layer 2 | After the first ultrasound (weeks 6 to 8), once there is an embryo and a heartbeat | Immediate family; very close friends; maybe your direct manager, if work needs adjusting |
| Layer 3 | After 12 weeks, when the risk of miscarriage drops dramatically | Extended family; your professional circle; friends in general; social media, if that's your thing |

Usually after the first appointment confirms everything. Earlier if there is exposure to chemicals or risky environments, physically demanding work, international travel, or a need for a lot of time off for appointments. Labor rights vary by country, but in almost all of them pregnant employees are protected from the moment of confirmation.
Social media is a separate decision. Ask yourself who actually needs to see it, and how you would feel if you had to announce a loss. People who are still trying may be affected: that doesn't mean you can't post, only that it is worth considering. Posting is a choice, not an obligation.
And when someone asks "Are you guys trying?" before you are ready, a few answers protect your decision: "When there's news, you'll know." "We're on our own timeline." "I'd rather not talk about that right now." You don't owe anyone an explanation.
When to tell is Chapter 41 of Map to the Positive, in Station V (Positive), between the first-trimester warning signs and the chapter on getting through the anxiety of the beginning. The book is the complete map from preparing to conceive through the first 30 days after a positive. If one of the people you are about to tell is still trying, it may be a gentle thing to give her.
Take 30 days. If it does not give you more clarity than everything you have read for free so far, ask for a refund and you get every cent back. We cannot promise you a pregnancy. We can promise you will not be guessing.
