Twenty-one weeks and two days. If the anomaly scan raised a question, today is about the next conversation: who to see, who comes, and what to ask.
- Size this week
- about the size of a carrot
- Length this week
- around 26.7 cm from head to toe

Twenty-one weeks and two days. For most people the mid-pregnancy scan is a good day. For some, it ends with a sentence that changes the room. If yours was straightforward, read this once and keep it in mind for a friend. If it wasn't, this one is for you.
Your baby

Your body
The scan around 20 weeks checks the baby's anatomy (MedlinePlus), and sometimes it finds something that needs a closer look, or something nobody can explain yet. The NHS advice for this week is plain: if the news from your anomaly scan was worrying, talk through your options with a doctor or midwife (NHS).
That conversation may include more scans or tests, and it may include a referral. Genetic counseling can explain how a genetic condition may affect you or your family (CDC). Abnormal ultrasound findings cover a wide range, from the placenta to the amount of fluid to the baby's development (MedlinePlus), so what matters is what your result means, from the person who can read it.
Try today
The results conversation
Time: 20 minutes
Book the follow-up, and ask how long it will be and who you'll see.
Decide who comes with you: your partner, or the person you'd most want beside you.
Write every question down first. What exactly did the scan show? Is it certain or possible? What tests come next, and what do they involve? When will we know more? Who do we call before then?
Ask whether genetic counseling would help (CDC).
Give the list to the person with you, and ask them to write down the answers so you can listen.
Make it work:Ask for the findings in writing before you leave. In the moment, almost nobody remembers what was said.
Watch for
Normal
shock, numbness, crying in the car park, not taking it in.
Call your provider
with any question that comes up between appointments; MedlinePlus says to tell your doctor or midwife about any problems or concerns (MedlinePlus).
Normal
a tense, aching body after a hard week.
Call your provider right away
for moderate to severe cramping or low abdominal pain, or any bleeding (MedlinePlus).
Normal
sadness that comes in waves.
Call your provider
for scary, upsetting thoughts that don't go away, or extreme sadness or anger; depression and anxiety can be treated, and the sooner you start, the sooner you feel better (AAP).
For you
You don't have to decide anything today, and you don't have to know how you feel about it yet. Waiting for more information is hard, but it's allowed.
Ask your provider what support exists where you are. In the UK, the NHS points to a free helpline for this (NHS); elsewhere, your clinic will know the local equivalent.
If you're the partner: you heard the same sentence. You're allowed to be frightened too. Go to every appointment you can, carry the questions, and tell someone other than her how you're doing.
