Your Body

Although it is most likely that you don't know yet that you're pregnant, this is the first week where you can get a positive result if the menstruation period didn't come. Observe your body, you may be more sleepy than normal or having more urination. To be more accurate you will have to wait another week until your body starts to produce sufficient amount of the hormone HCG (Human Chorionic Gonadotropin), this hormone is detected when a woman is pregnant.

 

Tips:

The Kilograms you should gain during the pregnancy depend on your weight before pregnancy. Body mass index (BMI): The Body Mass Index is a measure of association between a person's weight in relation to height. It is also important to take in consideration the kilos that will affect your health and your baby's health. Women who weigh less with BMI below 18.5 will gain weight between 13 to 18 kilos. Women who have a normal weight with BMI between 18.5 and 24.9 will increase about 11 to 16 kilos. The overweighed women with a BMI of 30 or higher will gain weight from 5 to 9 kilos. If you're going to have twin or more you will probably have to gain more weight, in all cases consult your gynecologist.
