Answer:
Pregnancy is actually a pretty complicated process that has several steps. It all starts with sperm cells and an egg. If semen gets in the vagina, the sperm cells can swim up through the cervix and uterus and into the fallopian tubes, looking for an egg. They have up to 6 days to find an egg before they die

Pregnancy:
After ovulation the ovum reaches the fallopian tube & fertilization takes place.
The fertilized egg undergoes development & it is implanted in the uterus. The corpus luteum continues to grow& produces large amount of progesterone. This results in pregnancy. Normally , it lasts for 280 days, at the end of which parturition takes place.
