What should you know about multiple pregnancy amboss?

Twins and other multiple pregnancies can be formed from one fertilised egg that divides or from separate eggs fertilised in the same cycle. Ultrasound helps identify the number of babies, their growth and whether they share a placenta or amniotic sac. Those details affect the timing and type of monitoring. Multiple pregnancy can bring more physical strain and a higher chance of pregnancy complications, so appointments may include blood pressure checks, urine testing and scans to assess growth, fluid and blood flow. Your maternity team will explain which findings apply to you.

Keep your antenatal appointments and tell the maternity team about headaches, visual changes, swelling, bleeding, fluid loss, contractions or reduced movements. Eat regularly, rest when needed and take only medicines approved for pregnancy. Growth monitoring may include a [Growth Scan](/treatments/pregnancy-and-birth-care/growth-scan/). Discuss where and when birth is recommended, which positions the babies are in, pain relief options and whether a [Caesarean Section](/treatments/pregnancy-and-birth-care/caesarean-section/) could be advised. The plan may be updated as the pregnancy progresses.

Contact your maternity unit urgently for vaginal bleeding, leaking fluid, regular contractions, severe abdominal pain, a severe headache, visual disturbance, sudden swelling, chest pain, breathlessness or noticeably reduced fetal movements. Do not wait for the next appointment when these symptoms occur. The maternity team can tell you where to attend and whether an immediate assessment is needed.

Ask whether the babies share a placenta or sac, how often growth scans are planned, and which symptoms require same-day assessment. Discuss recommended birth timing, delivery options, neonatal support, monitoring during labour and what to expect if one baby’s growth differs from the other.
