Development and Growth Of Mother and Baby in every passing week of Pregnancy

Pregnancy Week 1-4

A woman usually ovulates 14 days before her next menstural period. To simplify the matter, the start day of the pregnancy is considered to be the first day of the last menstural period(LMP). Actually, the conception takes place in the 2nd week of pregnancy. By week 4, your body start showing early signs of pregnancy as breast tenderness and fatigue. But in many case they go unnoticed till week 5. Some women may confuse implantation bleeding with menstural bleeding.

However, it is around the end of week 5 the pregnancy test start showing positive. The lining of uterus is getting thickened. The pregnancy is not detectable on ultrasound until the start of week 6.


This week may see the beginning of some of the early signs and symptoms of pregnancy such as morning sickness and breast tenderness. You may see some bleeding due to implantation of the foetus into the lining of the uterus By the end of week 5, you may be able to see baby in the ultrasound. A heartbeat can be seen. You will see a yolk sac which supports the fetus for 12 weeks and then disappears by 12 weeks.


The harmone levels are rising which may cause nausea, vomitting and headaches. You may feel extremely tired as your body is changing to support the fetal development. The levels of pregnancy hormone are enough that urine tests that measure hCG will show a positive result at this point. The central nervous system, the brain and the spinal cord, muscles and bone formation will also begin to start taking shape this week . The length of your baby is about 4 - 6 mm or 0.15 - 0.24 inches. At this stage, heartbeat is quite prominent, beating at about 100 beats per minute.


The breast continue to increase in size and nipples become more darker and erectile.The placenta starts functioning and doing more than just producing hormone hCG. Level of progestrone also increases, it may cause constipation for some women. Your baby is about 1 cm or 0.4 inches in length, (approximately the size of a grain of rice). As the large blood vessels form during this time, the heart begins to pump fluid through and baby's first red blood cells are created.


The heart begins to work harder at this stage, raising the volume pumped by 50 %. The increased blood flow passes through kidney, resulting in more urine output and causing you to go to the toilet frequently. If you notice any amount of blood spotting, do immediatly report to the doctor, it can be a serious concern. Your baby is about 1.5 cm or 0.5 inches in length. Eyelids fold are beginning to form . The tip of the nose is now present. Ears are beginning to form both internally and externally. The back muscles are growing along the spinal column, and his or her reproductive organs have started to form and soon will become either testes or ovaries.
