Here’s everything you need to know about your baby’s growth, from conception to birth:


Fertilization takes place when a sperm comes in contact with an egg and successfully penetrates it, experts also refer to this as conception. When this takes place, it completes the entire genetic makeup of the baby, even its sex. It takes nearly three days following the conception for the fertilized egg to quickly begin dividing into multiple cells.

Then, it gets transfers into the uterus by passing through by fallopian tube, and finally, it becomes attached to the uterine wall. Finally, the placenta starts to develop, which basically nurtures and nourishes the baby.
