Pregnancy Calendar - A Guide From Conception To The Birth Of Your Baby

It starts with first day of your menstrual cycle. In this period, conception does not occur, but your uterus is getting prepared for fertilization.

Your uterus is abundant with blood tissue and your eggs are maturing in one of your ovaries and getting ready to release one. From the day of your menstrual period, around fourteen to sixteen days, ovulation takes place (for a 28-day menstrual cycle period).

The sperm penetrates the egg in the fallopian tube. Although many sperms meet the egg, only one sperm enters your ovum and fertilization takes place.

After the ‘blastocyte’ enters the uterus, it will settle in one spot of your uterus. Now, these cells split into two groups; one that forms the placenta and the other that forms the baby.

The embryo develops in layers, ectoderm (outer layer), mesoderm (middle layer), and endoderm (inner layer).

Your baby is 1/17 of an inch long. This is the rapid growing week. In this week, your baby starts to have heart beating and the arms and legs will be formed along with some other organs.
