During the mid point of a womans cycle an egg is released from her ovary and begins its journey down her fallopian tube. It is at this point that a woman is most likely to get pregnant.
After a man's sperm fertilizes a woman's egg it takes approximately 10 to 14 days for the egg to work its way down a womans fallopian tube, and implant itself into the wall of her uterus. Once this happens, the woman's body chemistry begins to change, and these changes can be detected in her blood and urine.
Some early common symptoms of pregnancy include: frequent urination, nausea, missed period, breast tenderness, tiredness, mood swings, dizziness, and change of appetite.
