Having learned about our pregnancy and moving away from the first emotions, we begin to wonder: And what is the period already?
The most accurate ways
When I began to think about this issue, I began to learn how to determine the time. It turned out very simply. Obstetric term is the most common and it is sent on maternity leave and put the date of birth. It is considered from the first day of the last menstruation. I found out at 8 weeks since I have a long cycle and delays are the norm.
Then there was an ultrasound to confirm. They said 9 weeks and it coincided with obstetric period. Ultrasound is determined by the size of the baby, which correspond to the period of development. The longer the period of pregnancy, the greater the likelihood of an error in the term of the delivered ultrasound, because each child then develops in his own way. This period may be more or less for 2-3 weeks.
Each time I was given a slightly longer obstetric period. But I do not think this is a mistake, because the child himself knows when to come to this world.
But here on the examination of the doctor, when I became registered, I was told the term is less. I think the human method is the most erroneous. Ectopic pregnancy is generally impossible to determine, only for long periods.
By the way, closer to the end of pregnancy, doctors measure the height of the uterus, it is equal to the term.
In the early stages, they are still being tested for the level of hCG, but I didn’t give it up; I didn’t have to, because I found out about the pregnancy right away.
Until I read the correct information, I thought I could determine it by the day of intercourse. It is not true. After all, conception occurs on the third day after it, and after conception the embryo appears in the uterus only after 6-7 days. Only after this begins the period of pregnancy.
It seems to be such a simple question, determine the duration of pregnancy, and so many nuances. What is most like when you start to study any question, you will learn a huge amount of information and nuances.
