Inconclusive Scan

Your sonographer will have explained to you that you need another scan because he/she has been unable to confirm your baby’s heartbeat. The sonographer has seen that your pregnancy sac is in the womb but is too small to conclusively confirm a baby with a heartbeat. We understand that this is difficult for you and that you will naturally be feeling very anxious. The UK has very important and specific guidelines about re-scanning women in early pregnancy. This is to ensure that you receive accurate and clear information and the right standard of care.

The 2 main reasons for you needing to have a rescan to assess your early pregnancy are:

  • Your pregnancy is earlier than your dates would suggest. You may know precisely the date of the 1st day of your last period but it is impossible to know when you ovulated and therefore impossible to precisely date your pregnancy until your baby can be measured by a sonographer.
  • There is a problem with the development of the pregnancy.

Vaginal scanning has allowed the sonographer to see the detail of your tiny pregnancy much more clearly but a scan can only be accurate within 5 days and so dating a pregnancy between 4 and 6 weeks is not as accurate as after 6 weeks of pregnancy. Your second vaginal scan in 2 weeks will be able to confirm any change.

The waiting is hard, but it is important to allow 2 weeks so that the scan can confirm any change conclusively. The sonographer is only able to tell you what she can see today and will have explained this to you.

While you wait for the scan in 2 weeks we know you will, of course, be anxious, so we have included the contact details for local Early Pregnancy Units if you feel you need to call them for advice. You can call them even if you have booked your next scan at firstScan @ Window to the Womb.

If you have been prescribed any medicines, please continue to take them or talk with your doctor if you have any concerns.
