Important limitations
Pregnancy timing varies from person to person. Menstrual cycle length, ovulation timing, embryo transfer dates, ultrasound findings, and medical history can all affect the accuracy of a calculator result. Our tools are intended to help you understand pregnancy timing, not to replace individualized clinical care.
When to seek medical help
Contact a healthcare professional immediately if you experience severe abdominal pain, heavy vaginal bleeding, dizziness, fainting, shortness of breath, fever, or any other symptom that feels urgent or concerning.
