They usually recommend that you wait until your 20 week scan so that they have more of a chance at determining it through ultrasound. However you can tell on some babies as early as the 12 week scan. It all depends on the babies position and how miuch water you have drank to get a clear picture.

If an ultrasound at 14 weeks showed your due date as Oct 2 and an ultrasound at 20 weeks showed the same but a 28-week scan gave a Sept 23 due date could you have conceived before Dec 12?

Absolutely not. The later in pregnancy the less accurate the scan. The first two giving a due date of October 2nd will be correct and give you a conception date of around January 9th.

At which month is it necessary to do an ultrasound scan because some doctors say 3 months and some say 5 months?

It is not NECESSARY to do an ultrasound at all, they have only been done for the last 25 years or so and women were having babies for thousands of years before them. Having said that..... If you are unsure of your dates or you have bleeding you may have an ultrasound for dating and to check you are not miscarrying at 6-7 weeks. There are blood tests done for genetic abnormalities and a test for Downs syndrome where the scan is done at 12-13 weeks. (this would be the 3 month scan) If everything is normal and you are not having these tests most women have a scan at 18-20 weeks as at this stage the baby is fully formed and all its systems can be checked. (This would be the 5 month scan). There are no guarantees that the scan will pick up ALL abnormalities as some just cannot be seen on a scan. You do not have to have a scan at all if you don't want to it is totally up to you if and when you have it.


Can twins be missed at 12 week scan?

Yes, it is very common for one twin to hide behind the other and be missed on the scan. That's what happened to my best friend's mum, she went for a scan suspecting she was having twins, and they told her it was one baby, when she went for her 12 week, it turned out she was actually pregnant with triplets, they hid behind each other. Keep your fingers crossed & good luck xx
