What should you know about two weeks pregnant with twins?

Pregnancy weeks are counted from the first day of the last menstrual period, before conception usually occurs. At this point there may be no pregnancy to see on ultrasound. Twins develop when two eggs are fertilised or one early embryo divides, but symptoms cannot distinguish a twin pregnancy from a singleton pregnancy. A later ultrasound confirms the number of pregnancies and helps identify whether the babies share a placenta or amniotic sac, information that shapes follow-up.

Arrange antenatal care, take folic acid as advised, avoid alcohol and smoking, and review regular medicines with a clinician. Do not use the intensity of nausea or a home test line to judge whether twins are present. Once twins are confirmed, your team may arrange additional appointments and scans, including a [Growth Scan](/treatments/pregnancy-and-birth-care/growth-scan/). Discuss delivery planning early; a [Caesarean Section](/treatments/pregnancy-and-birth-care/caesarean-section/) is one possible route but is not automatically required.

Seek urgent advice for heavy bleeding, severe or one-sided abdominal pain, shoulder-tip pain, fainting, or marked dizziness. Early pregnancy symptoms with these features can require prompt assessment for ectopic pregnancy or another urgent problem.

Ask how your dates were calculated, when an ultrasound can confirm location and twins, which supplements are suitable, and whether any medical conditions or medicines need special planning. Ask how twin care differs from routine antenatal care.
