Yes, trust me my wife and I know from first hand experience. The doctor didn't know until about 2 weeks before they were born.
I'm pretty sure you can't tell the sex of unborn babies by their heartbeats...
You will find two heartbeats at the ultrasound.
If it is your own, yes. If it is fetal, no. You have twins.
No two heartbeats are the same.
Yes, Little Miss Twins are characters from the Mr. Men and Little Miss series created by Roger Hargreaves. They are two separate characters in the series, not actually "Mr. Men."
It's your own pulse/heartbeats. if you think it's the fetus' it is not. You can never feel the heartbeat of the baby.
No not necessarily
If there are two twins, the answer is 2 If there are two sets of twins the aswer is 4
During the first two months of pregnancy the unborn child is known as an embryo.
two babies not be visible due to the way a baby is lying in the uterus so each is not detected each time an ultrasound is done. an accurate way is hearing two heartbeats at the same time of taking the mother's pulse to make sure that one of the pulses is not the same as the mother.
Two stars
It is possible that: you only have one baby, not two; one baby is hiding the other; the two heartbeats are synchronized so you only hear one.
