It means that you don't really respond to outside stimulus with very much emotion or with the same behaviorisms that most other people would in the same situation. Let me try to give you an example. Say someone tells you that the sky is blue. Normal affect would be baseline, meaning your usual facial expression.
The fetusâ heart begins to beat at 5 weeks gestation, at around 80-85 beats per minute. This rate increases about 3 beats per minute per day during the first month. When the fetus heart is first developed it resembles that of a tube. As the fetus begins to grow, so does the heart. Due to lack of room, that tube begins to bend and twist, beginning to take on the shape of a normal human heart.
In general, you will be able to hear your baby's heartbeat when you are about 8 weeks pregnant using an obstetrics ultrasound. Or you may be able to hear the baby's heartbeat during regular prenatal care visit at 10 weeks, or more commonly at 12 weeks, with a fetal Doppler. The new fetal care technologies now allow for a much more specific time frame. We now know that your baby's heart begins to beat around 6 weeks after conception.
