Knowing the Age Pregnancy

All pregnant women will want to know how old her pregnancy. By knowing the gestational age can be calculated when your baby will be born. Babies born just months is expected, ie at 36 weeks gestational age plus 7 days. Here is how to determine gestational age:
1. The first day of last period (HPHT)
The trick with Naegle formula:
(Day +7), (month-3), (year +1)
For example, if you HPHT July 9, 2009, the estimated delivery date is 16 April 2010. With a note:
This formula is suitable if you are a regular menstrual cycle, ie 28-30 days. If your cycle is less or more, it must be corrected. For a short menstrual cycle, the estimated day of delivery will be reduced, whereas long menstrual cycles should be added
The weakness of this method is that many pregnant women who forgot her when HPHT. No wonder that about 5% of pregnant women experience childbirth more than the expected time. That sebabanya, you are advised to check ourselves when the menstrual late at least one month, so that HPHT identified accurately.
2. Ultarsonografi (USG). Physician determines the gestational age and estimate the time of the birth of a baby based on the "image" a fetus that appears on the screen.
4D Ultrasound accuracy rate reached 95%, if used at first trimeseter and using transvaginal ultrasound. Transvaginal ultrasound examination is the best choice for mothers who are obese, her womb "dived" into the past or her bladder is not quite filled.
