During the final stages of your pregnancy you may be offered screening and other tests to check that you and your baby are healthy.
It’s your decision to have screening and other tests – your midwife (or specialist doctor) will give you information and support to help you to decide whether to have them or not. Scans in late pregnancy are usually only offered if your baby is not growing as expected.
Screening and other tests
You will be offered screening and other tests to check that you and your baby are healthy and well. These include regularly checking your blood pressure, urine (wee/mimi) and weight, the size of your baby ‘bump’ and your baby’s heartbeat and position. These tests are to check that your baby is growing as expected and you are not showing signs of any problems.
Testing for Group B Strep (GBS)
If you have previously had a positive swab for Group B Strep, you should have a repeat swab taken at 37 weeks. If you are found to have Group B Strep you will be offered antibiotics while you are in labour to help protect your baby. Group B Strep can make babies sick.

These are usually only offered if problems were picked up during the 18–20 week anatomy scan, to monitor the growth of a baby who appears to be smaller or larger than expected, or if your midwife thinks your baby is breech (bottom or legs first) in the last month of pregnancy.
Your midwife (or specialist doctor) will give you more information about these scans, including how much they cost and where you will need to go to have them.
