Particularly in the initial pregnancy stages, the changes that are taking place in the mother's body appear extremely sluggish. Simply because the numerous incredible occurrences are barely discernible by the naked eye, it in no way means that every week of pregnancy is anything apart from constantly changing.



Commencing from the time of conception and culminating in the newborn's arrival into the world, pregnancy is a continuous state of persistent development. Every week is characterized by new changes as well as development in both the mom and child.

To study each week of pregnancy, we can focus on a specific week of each trimester to understand plainly how fast the changes happen within a pregnant woman's uterus. It is in the sixth week of the first trimester, when the mother officially comes to know that she is carrying a child.

Now, by this time, the baby has developed heartbeats, but is just a mere one by one-seventeenth of an inch in length. It is this heartbeat, which indicates that the heart is pumping blood, circulating it throughout the baby's little body, and the rudiments of arms as well as legs have just started to form. In this period, facial features are barely discernable. However, each baby as well as each pregnancy is quite distinct and hence this is just a guess estimate of the way things may advance by the end of the sixth week of pregnancy.

Skipping ahead by a couple of months, we now center on the twenty-first week of the second trimester of pregnancy. In this phase, the baby starts to stir quite a bit. The father, as well as other near and dear ones can also get to feel the tiny one stirring in the mother's belly. The rate of growth drops slightly as the heart grows to be more sound.

In addition, to assist with all this moving about, the baby's legs tend to become more balanced in relation to the remaining part of the body. The mother, in all likelihood feels much better since the morning sickness phase is well past her. It is during this time that people start to notice that she is pregnant.

Finally, in the third trimester of pregnancy, the delivery date looms large. The thirtieth week comes right at the halfway point of the third trimester. Now, at this phase, the baby in all likelihood weighs in at around three pounds and it is fast adding weight every day. This signifies that the mother is perhaps feeling a wee bit unwieldy and discomfited. The baby is able to move its eyelids.

The thirtieth week of pregnancy is marked by the baby's capability of producing its own red blood corpuscles. This indicates that the baby's bone marrow is presently functioning on its own accord and without any assistance from the mother.

Regardless of feeling that the pregnancy continues for ever and ever by most pregnant moms, each and every week of pregnancy is marked by something new and exciting. The mom-to-be as well as the baby are in continuous motion readying themselves for the concluding stages of this delightful and thrilling period.
