The first signs of pregnancy is the absence of menstruation. If you at the same time breast tenderness and morning possibly nausea feel, it is very likely that you are pregnant. Note: The absence of menstruation is not in itself sufficient evidence of a pregnancy.
How do doctor or midwife calculate the time of birth?
The exact date of birth of their offspring nobody can define. However, the doctor or the midwife is able to greatly narrow down the time of birth. The duration of pregnancy counts from the first day of the last menstrual period – even if the moment of conception until about 14 days later with the ovulation occurs.Following this pattern, you are on the date on which you became pregnant, by calculation by the third week of pregnancy. Overall pass about 40 weeks before your baby sees the light of day.
To find out the date of confinement, proceed as follows:
- Take the first day of your last menstrual period and add 9 months and 7 days to this date.
However, there are factors that affect the delivery time.Maximum cases deliver within plusminus seven days of this date.
Can the doctor decide whether the calculated date is correct?
Doctors can correlate this expected date of pregnancy with ultrasound examination. By simply assessing the growth of your baby as per his intrauterine age.
