It still feel surprised to see how excited few ppl are to know gender of the baby even before their growth is completed. Most important is baby and mother's health

Fetal heart rate range during pregnancy can be between 110-170 and this does not indicate the sex of the baby. It varies as per the stage of the Pregnancy as well as the current activity level of the baby.

Hey dnt belive that one heart rate is155 means boy r girl. Focus on your health....

Boy or girl cannot be determined like that. Take care of yourself and do refer to BabyChakra's articles for any tyoe of assistance in your Journey

I don't believe in such things but it's usually said that if the heart rate is more than 140bpm then it's a girl. Just focus on your diet and hope for a healthy baby.
