Within this information, we may use the terms "woman" and "women". However, we recognise that not only people who identify as women may want to access this content. Your care should be personalised, inclusive and sensitive to your needs, whatever your gender identity.
University Hospitals Birmingham NHS Foundation Trust (UHB) runs one of only a few dedicated multiple pregnancy clinics in the country. We're here to support you if you're pregnant with two or more babies. We want you to feel cared for, empowered and informed throughout your pregnancy, and we'll be with you every step of the way.
There will be more appointments for multiple pregnancies than for women pregnant with one baby. It's important that you attend all your appointments because of the increased risks that come with multiple pregnancies.
Our team includes:
- a lead specialist multiple pregnancy/foetal medicine consultant
- specialist multiple pregnancy/foetal medicine midwives
- a specialist multiple pregnancy/foetal medicine maternity care assistant
- your community midwife
This service is based at Heartlands Hospital, with appointments held in the antenatal clinic.
Attending your appointment
-
Please being a fresh mid-stream urine sample to all appointments at the multiple pregnancy clinic.
-
Please attend 30 minutes before your appointment time to allow us to check your blood pressure and urine.
-
As we provide personalised care to each patient, appointments can last a long time. You may want to bring a drink, a snack and something to read or do.
Different types of twins
For medical purposes, there are three types of twins. These apply to triplets too, although a triplet pregnancy will be more complex than a pregnancy with twins.
-
Dichorionic diamniotic (DCDA) twins
Each baby has their own separate placenta and separate sac.
All non-identical twins and some identical twins are DCDA.
-
Monochorionic diamniotic (MCDA) twins
Babies share a single placenta but have their own separate sacs.
Most identical twins are MCDA.
-
Monochorionic monoamniotic (MCMA) twins
A rare pregnancy type where babies share both a placenta and a sac.
Very rarely, identical twins are MCMA.
