When a mother-to-be buys a test and sees on it2 stripes, she can't wait to find out how accurate the result is. Of course, there is a possibility of error, it exists even if you take a test for the hCG hormone. The most accurate way to confirm pregnancy is an ultrasound. When should you undergo this procedure to make sure that a new life has begun in you?

- Transvaginal - gives the most accurate result. The sensor is inserted directly into the vagina. Conducted with an empty bladder. This method allows you to see the gestational egg on the 3rd week at a level of hCG more than 1800, sometimes even before the delay of menstruation.
- Transabdominal - the accuracy of the testimony is much lower, is carried out with a filled bladder - at an early stage, and empty - at a later stage.
But even if there is a fertilized egg, it can be without an embryo. For sure you can find out if this is a real pregnancy at the 5th week. Just at this time, the fetus has a heartbeat.
Why it is necessary to exclude an ectopic pregnancy before the delay?
Seeing pregnancy in the 3rd week will helptransvaginal ultrasound. It is important to do it right away to rule out an ectopic pregnancy - the development of a fertilized egg not in the uterus, but in the fallopian tube. And although the probability is small, only 2%, such a pregnancy threatens the woman's life. Therefore, its timely detection will help save a woman's health and life.
How long and why is it important to determine a multiple pregnancy?
If the fertilized egg has implanted inuterus, but the uterus is too enlarged, the doctor prescribes an ultrasound to find out if the pregnancy is twins or triplets. Early diagnosis of multiple pregnancy, which must be done between 6-9 weeks, will allow you to determine the number of twins. This is especially important if the expectant mother has undergone infertility treatment or IVF. If multiple pregnancy is determined, then you need to find out what kind of twins you have. They are:
- Monozygous or identical. In this case, they are always of the same sex, with identical DNA (100% coincidence), fed by one, sometimes 2 placentas. They develop from a single egg cell, which is divided and forms several embryos.
- Dizygotic or fraternal. Each embryo develops from its egg, has its own placenta and its DNA code, which coincides with a brother or sister by 50%. They can be both one and different sex.
Between the 9th and 14th weeks the doctor on ultrasound 100%will tell how many embryos develop, and whether they share one placenta. Identical twins with a common placenta are at risk for complications. One of the babies without proper medical care can be badly hurt. But if a doctor prescribes a treatment, babies will be born healthy. Wusi is a diagnosis that helps mothers learn about problems in time, solve them and give birth to a healthy baby.
