Honestly, the vast majority of diagnosed miscarriages are in fact miscarriages. We do believe, though, that a fairly large number of women who are diagnosed with a blighted ovum AND have a retroverted uterus are misdiagnosed especially if they are diagnosed at eight weeks or before.
here is a lot of talk on the internet of people being misdiagnosed with a blighted ovum. Although this has obviously happened, these cases are rare and with some of the high tech ultrasound equipment available these days it is very unlikely to happen – particularly where 3d scan equipment is involved.
Misdiagnosed blighted ovums are more likely to occur much earlier on in the pregnancy – for example nearer or before the 6 week mark where there is not so much to see in the ultrasound anyway, and dates can be wrong by a few days.
If you are in any doubt about your blighted ovum diagnosis, you should seek a second opinion. But most doctors will perform successive ultrasounds over 1 or 2 week intervals to confirm that a blighted ovum has occurred. Any treatment recommended will only be after due consideration and in most cases doctors will recommend waiting for a natural miscarriage.
So, although we may all want that hope that blighted ovum is the wrong diagnosis and we will go on to have a healthy baby, that must be tempered with realism so that expectations are not raised to an unrealistic level. Blighted Ovum misdiagnosis is extremely rare.
