Here are some commonly discussed early signs that may suggest a twin pregnancy, though none are definitive without medical confirmation. What to know
- Symptoms can be more pronounced: many people with twins report stronger nausea (morning sickness), greater fatigue, and higher appetite leading to quicker weight gain in early pregnancy. These symptoms are not guaranteed indicators, but they occur more frequently in twin pregnancies for some individuals.
- Early fetal indicators: some people notice movement earlier or feel movement in more than one location as early as the first trimester, though this can be difficult to distinguish from singleton pregnancy in early weeks.
- Physical measurements and tests: an unusually rapid rise in hCG levels or higher AFP screening results can raise suspicion, but these markers are not conclusive and require follow-up imaging.
- Ultrasound confirmation: the most reliable method to confirm twins is an ultrasound, typically around 11–14 weeks for a first accurate assessment, though earlier scans can detect multiples in some cases.
Key signs that might prompt discussion with a healthcare provider
- You report very severe nausea and vomiting that interferes with daily activities more than usual for early pregnancy.
- Substantial fatigue that is difficult to manage and doesn’t improve with rest.
- Pronounced weight gain or appetite changes beyond what’s typical for early pregnancy.
- Quick or unusual abdominal growth relative to gestational age, or tenderness in breasts beyond typical early-pregnancy changes.
- A positive screening result (e.g., from hCG-related tests) that is higher than expected, though this alone doesn’t diagnose twins.
What to do
- If you suspect twins or have unusual symptoms, schedule a prenatal visit promptly.
- Discuss ultrasound timing with your provider; a first-trimester ultrasound is commonly used to assess numbers of fetuses and shared placenta status.
- Maintain regular prenatal care, including nutrition, hydration, and monitoring for dehydration or excessive fatigue.
