If you were an average weight before pregnancy, you should try to gain about 25 to 35 pounds during pregnancy. This weight gain seems to best nurture a mother and growing baby. At the minimum, a pregnant woman should gain 15 pounds. Women who were underweight before pregnancy may gain up to 40 pounds. Women carrying twins may gain as much as 45 pounds. Women who were overweight should limit their weight gain to 15 to 25 pounds.
Conception Achieved (Pregnancy)
The process of conception starts in the female reproductive organs. An egg is released into the fallopian tubes once a month to await fertilization. If a sperm reaches the egg and penetrates it, it is fertilized. Conception takes place during ovulation. This happens 2 weeks after the last day of your last menstrual cycle. If eggs are not fertilized, they are released through menstruation and process repeats next month.
