At 16 weeks pregnant, can the baby's weight and size become a nuisance for the expectant mother? How can you tell where your baby is at 16 weeks pregnant , and what causes lower abdominal pain at this time ? What has changed regarding your baby's movements – does 16 weeks mean you can finally feel them?
The sixteenth day of pregnancy is the time when you can read on the forum for mothers about surprising symptoms that are not very associated with pregnancy. Instead of nausea or fatigue, a woman of 16 weeks may experience gum pain and nose bleeding. There is also pain in the lower abdomen. The weight and size of the baby change dynamically, but for the future mother it is also important to take care of her own weight - weight gain is necessary for the proper development of pregnancy, but it is worth maintaining control over it.
16 weeks pregnant: what month and trimester is it?
Women in their 16th week of pregnancy usually have a good idea of what month and semester they are in. Doubts can sometimes arise when one month of pregnancy, or even a trimester, ends and another begins. To be clear, 16 weeks of pregnancy marks the end of the fourth month, but still the beginning of the second trimester. It's worth noting that, during a second-trimester ultrasound, the doctor also confirms the actual gestational age, estimated based on the first-trimester ultrasound.
The middle trimester is considered to be the least burdensome for future mothers due to the fact that the tiring symptoms of the beginning of pregnancy are already disappearing, and the size and weight of the baby do not interfere with everyday functioning too much.
Lower abdominal pain at week 16
The 16th week of pregnancy is a time when miscarriages are very rare, and lower abdominal pain that occurs at this stage is most often caused by the growing uterus. It is felt especially in the lower back, which is under increasing strain. If it resembles the discomforts associated with menstruation or PMS, it is normal and should be approached with caution. Heavy vaginal bleeding, possibly accompanied by cramps and abdominal pain, may indicate a miscarriage – if such symptoms occur, consult a doctor as soon as possible.
Some expectant mothers may be disappointed to learn that they are unlikely to feel their baby move at 16 weeks. This shouldn't be a cause for concern—you just need to be patient. You can connect with your baby through your voice and touching your belly. The fetus also responds to light, so it may become less active at night and more active during the day.
16 weeks of pregnancy: the weight of the expectant mother
Even women who have not gained weight so far, in the 16th week of pregnancy, begin to notice changes in their body, sharing their experiences on the forum.
What changes can be seen in the 16th week of pregnancy?
- Weight in the 16th week of pregnancy can increase by almost 0,5 kg. It is possible that this pace of growth will continue in the following weeks until the end of pregnancy. However, weight gain in pregnancy depends on the starting weight.
- According to various sources, the daily energy requirement increases at this stage of the 4th month of pregnancy to ensure the correct weight of the mother and baby by 150-350 kcal.
- The hips may appear wider than before as the pelvis prepares for labor and the fetus is growing rapidly in the womb.
- Due to the weight gain and the changing figure, slowly you have to start replacing your wardrobe with looser clothes.
A slight weight gain at 16 weeks of pregnancy is normal. In a twin pregnancy, it may be slightly larger, but only slightly - throughout the entire period of pregnancy, a woman with two babies in her belly should gain a little more than the other pregnant women.
The size and weight of the baby at 16 weeks of pregnancy
For now, the baby's weight doesn't contribute to the mother-to-be's weight gain – at 16 weeks of pregnancy, the fetus weighs an average of about 146 g. It begins to grow at its own pace, so it's no longer possible to precisely determine the week of pregnancy and the day of conception based on height and weight. At this stage, the fetus should measure about 18,3 cm.
It is worth being prepared for the fact that the weight of the baby will soon begin to burden the mother's spine.
16 weeks pregnant: where is the baby?
Since the baby's movements are still imperceptible to the expectant mother, it's no wonder there are questions about the fetus's position. At 16 weeks of pregnancy, the baby is located slightly below the navel , and the abdomen in this area begins to harden visibly.
At this stage, the fetus begins to acquire fatty tissue. Its eyes are still closed, but in the sixteenth week of pregnancy, its eyelashes and eyebrows begin to grow. At the 16th week of pregnancy, hearing begins to develop—the baby's sense of hearing is the first to develop. The fetus can hear its mother's heartbeat and the sounds of its surroundings.
During an ultrasound at this stage, you can find out not only where the baby is, but also many other parameters, for example its head circumference (HC ) – on average it is about 12 cm.
16th week: belly and pregnancy symptoms
The abdomen can become noticeably rounded at this time, which is why many women document this stage of pregnancy in photos. With mild symptoms at 16 weeks, expectant mothers may experience an additional surge of energy and even an improved libido.
The baby's weight isn't too heavy, and the uterus is already higher than at the beginning of pregnancy. This may help alleviate the constant need to use the bathroom, which can be a nuisance for expectant mothers in the earlier stages. However, intestinal problems are relatively common. One might assume they depend on the baby's location and weight at 16 weeks of pregnancy, but they are more likely a result of hormonal activity. At the same time, the gums and nasal mucosa may soften, which is why we often see questions about nosebleeds and gums in 16 weeks of pregnancy on the forum. Due to hormonal changes and the placenta's high blood demand, blood pressure often drops, which can lead to dizziness.
Ultrasound in the 16th week of pregnancy: girl or boy?
At 16 weeks pregnant, expectant mothers wondering whether they're having a boy or a girl can find out the answer during an ultrasound. The baby's size allows for a fairly clear view of the reproductive organs.
Of course, due to the baby's position and movements, it may not be possible to determine the truth during this particular ultrasound. If the fetus turns its back to the scanner, at 16 weeks of pregnancy it will still be unclear whether it is a girl or a boy. Expectant parents sometimes opt for a 3D or 4D ultrasound. This allows them to see the baby in a three-dimensional image from inside the abdomen, or even on video in the case of a 4D ultrasound. The genitals should then be more clearly visible, but under unfavorable circumstances, this test may not provide a definitive gender.
