gender predictor — for fun only
two old wives' tales: the Chinese Gender Chart and the heart rate myth. neither is medically accurate. if you want to know, the 12-week NIPT blood test or the 20-week scan are the real answer.
honest disclaimer:these methods are folklore. the Chinese Gender Chart accuracy in real studies is around 50% — same as flipping a coin. baby heart rate doesn't predict sex either (this was disproven in 2006). play with it for fun, then come back to a tool that actually does something useful.
1. Chinese Gender Chart
enter your age and the month you conceived. the chart was supposedly buried in a Beijing tomb 700 years ago. or made up last Tuesday. unclear.
2. fetal heart rate myth
the myth: girls' heart rates are above 140 bpm, boys' below. the reality: heart rate changes through pregnancy and varies wildly between babies. studies have shown zero correlation. but it's fun to check.
want to actually know?
two reliable methods in Australia — both safe, both medical, both about 99% accurate.
- NIPT (non-invasive prenatal test): blood test from 10 weeks. gives sex chromosomes + screens for trisomies. ~$400–$500 in AU, sometimes Medicare-rebatable.
- 20-week morphology scan: standard AU pregnancy ultrasound. sonographer can usually tell — but they're not always 100% sure if positioning isn't ideal.
