If i Am 19 weeks pregnant and heart rate is 140 what the sex?

The belief that a fetal heart rate of 140 beats per minute (bpm) indicates the baby's sex is a common misconception. There is no scientific evidence to support this claim. The fetal heart rate can vary significantly throughout pregnancy and is influenced by various factors such as the baby's activity level, maternal health, and gestational age. It does not provide a reliable indication of the baby's sex.
