Back pain during pregnancy is a very common condition, occurring in about 50-80% of pregnant women, affecting daily activities during pregnancy. For some pregnant women, back pain is only transient and insignificant.

Back pain during pregnancy is a common phenomenon but should still be taken into account by pregnant women. Changing posture, doing light exercises or applying some therapies can help improve this condition.

Normal blood volume in humans is determined by testing the hemoglobin (Hb) concentration in the blood. If the Hb concentration is below 13g/dl in men and 12g/dl in women, the subject is considered anemic. Pregnant women are diagnosed with anemia during pregnancy when the Hb is below 11g/dl.

Weight gain during pregnancy is very much related to the health and weight of the baby born. The mother's scientific diet, exercise and rest will help the baby develop optimally.

The second trimester is counted from week 13 to the end of week 27 of pregnancy. In the second trimester, the sex of the fetus can also be clearly seen and the pregnant woman begins to feel the movements of the fetus.

The second trimester of pregnancy is the period when the fetus develops strongly in both shape and brain structure. The weight of the fetus in the second trimester is one of the important factors in assessing the health of the fetus.

40 weeks pregnant, or 38 weeks post-conception, are both in the ninth month of pregnancy. The development of the fetus in 40 weeks is complete and there will not be many changes compared to a week ago, except that the hair and nails continue to grow.

Fetal development at week 37, or 35 weeks after conception, is generally quite complete. The mother's pregnancy is now almost full term, the baby is big and strong. Is the 37-week fetus turned yet? This is a common question at this stage.

At 23 weeks pregnant, your baby is almost developed enough to survive outside the womb. His lungs are getting ready to breathe by inhaling amniotic fluid. His brain is making the connections he needs to think — and one day communicate with you.

At 19 weeks after conception, the fetus has slowed down compared to previous weeks. At this week, the amniotic fluid surrounding and protecting the fetus can irritate the baby's delicate skin.

At week 9, the mother is in the first trimester of pregnancy and the fetus is only the size of a grape. At this time, the fetus has begun to have all its organs and is increasingly taking on the shape of a baby.
