Ultrasound - the anomaly scan

You will be offered an anomaly scan at around 20 weeks to check that your baby is developing normally.

There are different patterns in various parts of the country, so check what is available in your area with your midwife.

What is an anomaly scan?

Carried out between 18 and 22 weeks of pregnancy, this scan checks that the baby has developed normally and does not have a major ‘anomaly’ or problem. It won’t detect all problems, but it may show problems in the baby’s brain, heart, kidneys or digestive tract. In most cases it will simply show that your baby is growing well. The scan also checks the position of the placenta.

Do I have to have the scan?

No – it’s your choice. There's no confirmed evidence that ultrasound is harmful in pregnancy.
It can be a lovely chance to meet your baby but bear in mind that some women will be told that the scan has picked up a problem.

Take your partner, or a friend you can rely on for support, in case you need it.

Remember: scans will not detect every problem and sometimes suggest that there might be something wrong when there isn’t.

Im on my 18th week and My little ones movements are very strong. I feel baby kick and move ALOT! and my bump is very well there!! Ppl say im more advanced then my dates says but everyone is different, plus im quite pettite so maybe that has something to do with it. Im so excited about our 20week scan which will the day after boxing day :) cannot wait to find out what we are having, such a lovely xmas pressie :) .... labour and birth are a different matter, im already so scared about it!!! Roll on may!......
I will be 18 weeks tomorrow with my 1st baby...so far I don't see my baby bump but my hubby says that he does (its little according to him). I feel sometimes butterflies in my lower abdomen which I believe is the baby moving...(?) Can't still eat enough, don't have any cravings as yet. Feel like eating only when I am too hungry...used to love drinking milk but since this pregnancy started, I hardly had a cup of Milk....AND VERYYYYYYYYY Lazy....pffff....planned to go out for 30 min walking but.... Re Scan-We had to pay £5 to get 2 prints of our baby's 1st scan with a small standard cardboard frame, is it so?

Hi, I'm having my 20 week scan on Monday, just wanted to know can they tell me the sex of my baby because i know they had stopped at one stage. Really excited to know what i'm having!
They can only sex the baby from 16weeks onwards, and thats only if they catch baby in the right position! 9 days till my 20 week scan and im so excited to find out what im having!
hi every1, 3 weeks left for my first scan and m soooo exited. can any1 tell me will i be able to nw about my child's sex on week 13 or 14. thnxx
hi, im 9 weeks pregnant well i think i am. iv got my scan in 3 weeks. iv got so many questions i just don't know were to start!! :0)
Hi, im 16 weeks pregnant with twins!!!! Its my first pregnancy and im still in shock! haha. Ive got loads of questions about everything, just dunno where to start!! xx
Hi, I'm 18 weeks today, first baby. At my 12 week scan they told me that they wouldn't be able to tell me the sex as the genitals haven't delevoped enough to tell. They say from 16 weeks they can tell you. I think it depends on the hospital though cause I know someone who was told at their 12 week scan. No harm in asking, but remember won't be 100% so could change. I've now decided not to find out the sex, looking forward to the surprise on the day. Xx
Hi all! i am 18 weeks. This will be my second child. Am quite anxious as i suffered a miscarriage earlier in the year. I also found out that I have a cyst on my right ovary when I had a early scan. so far all is well, can't wait for my 20 week scan :o)
I am due for my scan Friday. Its my 12 week scan and the hospital that I'm going too tell you the sex. Any one had the 12 scan and been told the sex? So anxious about the scan.
Hi all, I'm 16weeks along and this is my 4th baby. Please do not be scared, nervous or anxious, you need to relaxe and embrace the moment. It's the most wonderful experience meeting your little baby. :) If you feel you can't relaxe then try looking at mindfulmammas online for relaxation guidance. I used their cd (£6) and just listened to it in the evening 2 or 3 times a week - if you give it a chance it really works. While I was having my last child I found that I was thinking about meadows of soft coloured flowers and it was the best birthing experience I've had!! It helped me with every aspect of relaxing and I kept a really good possitive attitude to it all. Hope this helps someone :o)
