Methodology
Womens Health Resource follows the pregnancy or cycle formula described on the page, such as last-menstrual-period dating, IVF transfer dating, cycle-window estimation, hCG trend context, or pregnancy-weight categories. It keeps date and range outputs educational because clinical dating and pregnancy assessment require obstetric history and, often, ultrasound or lab follow-up.
Assumptions
- Cycle-based estimates assume the entered period dates, cycle length, luteal phase, and pregnancy dates are accurate and reflect the user rather than a population average.
- LMP due-date estimates generally assume a 28-day cycle with ovulation around day 14 unless the calculator provides alternate inputs such as ovulation, conception, ultrasound, or IVF transfer date.
- Pregnancy and fertility outputs assume a singleton pregnancy or typical cycle unless the user has entered data that the calculator specifically supports.
Limitations
- Irregular cycles, breastfeeding, postpartum changes, perimenopause, PCOS, fertility treatment, pregnancy loss, multiple gestation, and uncertain dates can make estimates inaccurate.
- Ovulation and fertile-window estimates are not reliable contraception and do not confirm pregnancy, miscarriage, ectopic pregnancy, fetal growth, or pregnancy viability.
- hCG levels and pregnancy-weight ranges vary widely; symptoms, bleeding, severe pain, high blood pressure, or concerning lab trends need prompt clinical review.
