About

Early pregnancy involves rapid hormonal shifts. A single hCG value often causes anxiety because the "normal" range is remarkably wide. For example, on Day 16 post-ovulation, a normal value can range from 17 to 429 mIU/mL. This tool does not just list numbers. It compares a specific user result against median (P50) and outlier (P5/P95) statistical models. Understanding position relative to the median helps manage expectations better than comparing against a static table.

Low if x < P5Average if P5 ≤ x ≤ P95High if x > P95

Note: High levels may indicate incorrect dating or multiple gestation.

Frequently Asked Questions

DPO stands for Days Past Ovulation. It is a more accurate dating method than LMP (Last Menstrual Period) because ovulation day can vary. If you do not know your ovulation day, assume it was Day 14 of your cycle.
Implantation can occur anywhere from 6 to 12 days after fertilization. A later implantation means hCG production starts later, resulting in lower numbers on the same cycle day, yet the pregnancy remains perfectly healthy.
Statistically, twin pregnancies often show higher hCG levels, roughly 30-50% higher than singletons. However, there is significant overlap. A high P95 value alone confirms nothing; an ultrasound is required for diagnosis.
