If there are no periods, the test is "striped" or it does not show an interesting situation, then 10 days after the start of the delay, in any case, you should contact the antenatal clinic. A slight increase in the uterus by an obstetrician-gynecologist at this time can be determined manually when examining a woman.
Ultrasound 10 days from the day of delay gives fairly accurate indicators of the presence, absence and characteristics of the embryo. This does not mean that all, without exception, pregnant women at such an early date should go to the ultrasound diagnostic rooms and do ultrasound as they please. The effect of ultrasound on the embryo is not considered harmful, but it cannot be called useful either, it has not yet been sufficiently studied.
There are certain indications for which the doctor will recommend a woman to undergo an ultrasound procedure for such a short period of time:
• The delay is accompanied by unpleasant, painful sensations, there are discharges that are not menstrual;
• Previously, the woman had ectopic pregnancies, miscarriages in the early stages;
• If there is a delay, the test shows a positive result, and the size of the uterus and the features of the organ during palpation do not tell the obstetrician about the onset of pregnancy;
• If the woman has previously had uterine surgery, including a caesarean section;
• If the woman does not remember the date of the last menstruation.
Diagnostics with an ultrasound scanner in these cases will make it possible to establish whether implantation has occurred in the uterine cavity, whether a woman develops a tubal (ectopic) pregnancy, and also to determine whether there is a detachment of the fetal egg if there are abnormal discharges. It is in the early stages that it is possible to determine the gestational age to the nearest day, because in the embryonic period all embryos grow at approximately the same rate.
For women who have undergone surgery on the uterus, ultrasound will help to find out what condition the postoperative scar is in, whether the fetal egg is fixed in the scar area. If a woman does not have fears and a complex history, then there is also an urgent need for an ultrasound scan, and for the first time the expectant mother will be able to look at her baby at 11-13 weeks, when the doctor will give a referral for the first prenatal screening.
