First-trimester screening is optional
Screening tests give information about risk — they don't diagnose. Talk to your provider about what the results mean and what follow-up, if any, you would want.
How your baby is developing
Your baby is now about 5–6 cm and weighs around 14 grams. All the major organs, muscles, and bones are in place and continuing to develop. The face looks more human — eyes have moved from the sides to the front, and the ears are in their correct position.
Reflexes are beginning to develop. Fingers and toes are fully separated, and tiny fingernails are forming. The digestive system is practicing contractions, and kidneys are beginning to produce urine.

First-trimester screening
Around weeks 11–13, many providers offer first-trimester screening — a combination of a nuchal translucency ultrasound and blood tests that assess the chance of chromosomal conditions such as Down syndrome. This is optional, and your provider can help you decide whether it's right for you.
The dating scan (if not already done) confirms your due date and checks basic fetal development.
Sharing the news
Many people choose to share their pregnancy news around week 12, when the risk of miscarriage becomes lower. There is no rule about the right time — it's entirely your decision based on your comfort and circumstances.
Tips for this stage
Nausea may ease soon
For many people, morning sickness starts to improve in the second trimester. If yours continues past week 12–14, mention it to your provider — there are safe options to help manage persistent nausea.
Save your scan images
Your dating scan or NT scan images can be stored digitally or printed. Some parents enjoy keeping a small pregnancy journal or folder starting from this point.
