What does a pregnant woman feel during the twenty-first gestational week?
The pregnant woman already feels the movements of the baby more and more often. It is probably more than 10 times a day, considering that it makes more than 200 movements in 24 hours.
Some doctors recommend counting fetal movements within an hour. In this case, you should catch at least 4 as a minimum. Too little activity of the baby is a reason to consult a doctor.
Sometimes in the twenty-first gestational week, some women begin to feel a pulsation inside the abdomen. This may be the baby’s heartbeat.
As for personal sensations, it is still normal to feel a tightening of the ligaments on both sides of the abdomen. The tension on the organs is clearly palpable and sometimes uncomfortable. It is due to the baby’s growth.
The uterus squeezes the bowels and you may suffer from constipation from time to time. This discomfort can be influenced by adjustments in the food menu.
There are ongoing changes in a woman’s body. The mammary glands develop and begin to secrete. This can also happen earlier than the twenty-first gestational week.
There are women who already notice stretch marks appearing on the skin of the abdomen. Do not get unnecessarily upset. Take measures – consult what creams to apply. The belly will continue to grow.
The vaginal discharge should continue to have a slightly sour smell and be white or light in colour. The presence of pus, blood or other atypical characteristics is a reason to see a doctor. At this stage of pregnancy, the child is likely to survive if delivery occurs. However, you should not rush. It needs the nature-ordained nine-month development period.
If the vaginal discharge is watery, seek medical help immediately. This could be a sign of premature birth.
