Estimates, not medical advice
Pregnancy Calculator provides estimates for informational purposes only. Pregnancy dates can vary, and your healthcare professional can provide personalized guidance about your pregnancy. Results such as due dates, pregnancy weeks, months, trimesters and conception dates are based on standard averages and the information you enter. They are not a diagnosis and do not replace an examination, ultrasound or advice from a qualified professional.
General information only
Our week-by-week and month-by-month guides describe what commonly happens in pregnancy. Every pregnancy is different, and the timing of tests, scans and appointments depends on your country, your care provider and your circumstances.
When to seek care
Contact your midwife, doctor or maternity unit promptly if you have bleeding, severe or persistent pain, fluid leaking, a severe headache, changes in vision, fever, or — later in pregnancy — a change in your baby’s movements. In an emergency, call your local emergency number.
