The Baby’s Development @ Week 12 of Pregnancy
Tracking every small development happening within you can be fascinating. At week 12, the baby’s size is similar to that of a kiwi measuring approximately 5.4 cms and weighing nearly 18 gms. Some of the organ and system developments of the baby happening within the womb this week are,
Pituitary and pancreatic hormone secretion
Though many more developmental activities and maturing are lined up, at week 12, the pituitary glands have started producing hormones, and the pancreas has begun synthesizing insulin.
One of the best developments is that the bone marrow commences making white blood cells (WBCs)- the essential armors that help fight infections. While the baby is well-protected within the womb, these WBC’s will perform their actual defensive function post-birth.
Fetal Digestive Muscles Begin Contracting
The muscles of the baby’s digestive system start contracting and relaxing. The infringing small intestines on the umbilical cord completely move back into the baby’s abdomen.

- Avoid raw, unprocessed, uncooked, or partially cooked foods and meats. Also, make sure to avoid consuming unpasteurized milk and milk products as they can harbor listeria and other harmful pathogens.
- Take your prenatal vitamins regularly along with fresh fruits, vegetables, well-cooked and processed meat or fish such as salmon, tuna, etc., with no-mercury content. These can help you maintain good nutrition and healthy weight during your pregnancy.

Are there any immunizations to be given during the first trimester of pregnancy, on or before the 12th-week pregnancy?
The Centres for Disease Control and Prevention (CDC) recommends flu vaccination for pregnant women during the flu months of October to May to protect the mother and child from flu-related complications.
The National Immunisation Schedule for pregnant women advises taking tetanus and adult diphtheria (Td vaccine) vaccination during early pregnancy, followed by a second dose four weeks after the first dosage administration. It is required to check with the obstetrician on the requirement and the best time to take these vaccines.
Conclusion/ Take- Away
At the 12th week of pregnancy, you have only 6 months of pregnancy to go. Your baby bump may be distinct and visible to the outside world. But, even if your baby bump is not prominently visible, your doctor can feel the growing uterus during a physical examination or by simply touching the abdomen. The baby’s growth is phenomenal by week 12, where its size has doubled since the last three weeks of the first trimester. Consult the obstetrician for an impending ultrasound, vaccination, prenatal scan, pregnancy abnormalities, queries, and other information.
