The First Trimester of Pregnancy
Pregnancy is a huge process. The moment of conception is a miracle all on it's own considering the probability of one sperm fertilizing 1 egg. Conception can only happen within 2 days of ovulation. Those 2 days are very busy for the sperm that is traveling past the acidic cervical mucous up through the uterus to where they find the egg. By that time the number of sperm has decreased to about 200 and only one (or two in the chance of twins) will make it through the egg to fertilize it.
