It is a time between 14 weeks to 27 weeks of your pregnancy. At this time, many expectant parents want to see the baby during 4d ultrasound sessions at imaging centers. Some parents-to-be decided to have 2d ultrasound sessions at the beginning of the second trimester to find out the gender and 3d 4d ultrasound sessions in later weeks of the second trimester. The baby’s entire body could be seen usually until 22 – 23 weeks of pregnancy. After that, the baby is “too big” to fit into the ultrasound machine’s screen. However, the experienced sonographer would show your baby’s legs, arms, fingers, and other body parts in detail. The baby’s facial features are formed by 25 weeks of pregnancy. At this time, most babies’ faces look a little “skinny,” but very soon, the look would change to chubby with big cheeks. Our website has a page of weekly 3d ultrasound images where you can see the difference in the development of babies’ faces.
Baby’s growth during the second trimester by months
At the end of the second trimester, about 27 weeks, a baby’s weight is around 2 pounds and has a size of approximately 14 ½ inches from head to heel (could be compared with the size of cauliflower).
By now, the baby sleeps and wakes up at regular intervals and might suck on her fingers. Even though the baby started inhaling and exhaling amniotic fluid, her lungs are still immature. If she is born right now, the baby would be needed lots of medical help to survive. Moms could feel some slight movements because of the baby’s hiccups which could be regular issues. Those hiccups are usually short-timed, and they don’t bother the baby. Most recognizable facts of fetal development at this stage: the baby’s muscles are maturing, and the baby continues to gain weight.
Common symptoms during the second trimester.
Moms-to-be usually started to feel adjusted to a new condition mentally and physically. That is a reflection of endocrine and metabolic changes continued to develop in a mother-baby bonding. Production of progesterone and estrogen hormones would create chemical changes at the cellular level in the placenta to facilitate the growth and development of the fetus. As a result, a mother would also receive extra energy. All those changes would positively affect the mother’s mood and behavior. However, that also could lead to an unnecessary weight gain.
Weight gain in pregnancy
It is recommended that you gain some weight even though you are considered to be overweight already. The guidelines for weight conditions can be found on World Health Organization (WHO) website.
Ultrasound session during pregnancy
In our previous post, you can find more information about how extra weight influences the quality of 2d 3d 4d ultrasound during pregnancy.
How much weight would you gain?
During the first trimester a weight gain would not be substantial, probably about four lb. on average. The main concern would arise during the second and the third trimesters or after the 14th week of the pregnancy. The gain could be about 1 pound every week or so. Losing weight during pregnancy is not recommended. That relates to a fat-burning process that could be dangerous to the baby. The alternative could be developing some muscles under working out and healthy exercising that would be beneficial. After giving birth, that is especially important during puerperium or the so-called “fourth trimester.” The main benefits would be weight loss and fighting depression by increasing self-esteem.
Common side effects during the second trimester
As was mentioned before, pregnant moms would feel better during the first trimester. However, you might experience some consequences of your condition, such as low blood pressure, leg cramps, frequent urination, higher hurt beet, and back pain.Some women would also experience varicose veins, mole growth, and stretch marks.
