First Month

0-2 weeks

During ovulation an egg is released from the ovary. If intercourse happens and the sperm cells successfully swims its way to the uterus, fertilization will occur in the fallopian tube. This would lead to the formation of the embryo which would attach itself to the lining of the uterus by day 6.

3-4 weeks

During that time, your baby would be the same size as a poppy seed.

At this point the mother would have noticed that her period didn’t come. The embryo would start having organs and become curved.

A thin tube, which will eventually become the spinal cord, starts to form along the length of the embryo,

Bump looking structures begin to form around the structure which would eventually become the arms and legs.

During the 3 to 4 weeks, the embryo would grow to the length of 0.6 cm.

Second Month

5 to 6 weeks

Your baby would have grown to the size of a pea. It is now about 1.4 cm. The brain would start growing faster than the other parts of the body so mostly the head would be noticeable. The heart starts developing at this stage and a heartbeat can be heard through an ultrasound.

The umbilical cord joins the placenta to the embryo, which would provide the embryo with the necessary nutrient.

7-8 weeks

From a pea to a raspberry. During the 7 to 8-week mark, your baby is now about 3.1 cm. The shape of the embryo starts to straighten out.

The fingers and toes are nearly done forming. The basic organs have formed and these would include parts of the brain, heart and kidney.
