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.
You're likely to hear your baby's heartbeat for the first time at your dating scan. This usually happens between 10 weeks and 13 weeks plus six days, although your baby's heart will have been beating from about six weeks onwards. Hearing your baby's tiny heart beating for the first time is an exciting moment. You'll hear a rapid drumming sound that's about twice as fast as your heartbeat. Your baby's heart beats between 110 times and 160 times per minute. You may also hear your baby's heartbeat at one of your antenatal appointments. Your midwife is unlikely to listen for it while you're still in your first trimester, as it can be hard to detect at this stage.
