Question: How often can I do a pelvic ultrasound during pregnancy without harm to he alth? The doctor is already prescribing my fourth examination in a month, and I heard: although this is not an X-ray, it is also not such a harmless procedure.
Answer: There is no strict regulation that determines how many times you can do an ultrasound during pregnancy, and how much is harmful. There are certain terms for performing ultrasound during a normal pregnancy, but if problems arise and without ultrasound it is impossible to assess the situation and decide on further treatment tactics, then the number of ultrasounds is determined by the specific clinical situation. In general, ultrasound is considered a harmless procedure for the fetus, but it is impossible to say that this type of study has no effect. The fetus feels the fact of the ultrasound, however, there is no evidence of its damaging effects. It all depends on the situation: if there is a threat of pregnancy, ultrasound is used as many times as necessary to ensure the normal course of pregnancy. It's just not worth doing an ultrasound once again during pregnancy.
Q: Can I artificially delay my period? I am taking a hormonal contraceptive, can I stop taking it not on the 21st day, but 2-3 days later if necessary?
A: Yes, it is possible, but only if you are taking a monophasic drug (there is no "tri-" prefix in its name). Modern hormonal contraceptive regimens require longer use the most common scheme now is 63 + 7, that is, you take three packs in a row without a seven-day break (21 + 21 + 21 \u003d 63) and only then take a break for seven days.Thus, you can easily cancel your period and transfer them to any time convenient for you without harm to he alth.
Birth of the corpus luteum
B: Approximately in the middle of the cycle, I begin to have pain in the mammary glands and in the lower abdomen, after a couple of days everything goes away. What does this mean?
A: This is normal. With the beginning of each menstrual cycle, a follicle (“vesicle” in which the egg matures) begins to grow in your ovary. By the middle of the cycle (12-14th day with a 26-28-day cycle), this follicle bursts (the process is called ovulation) and an egg comes out of it. A corpus luteum forms at the site of the ruptured follicle. The process of ovulation is accompanied by a sharp change in the concentration of certain hormones. Some women do not feel this, nor do they experience pain when the follicle ruptures, while others feel both ovulation and hormonal fluctuations.
Analyses according to the rules
A question of interest to many: on what day of the cycle should I take tests for hormones and which hormones?
• A blood test for sex hormones is taken on the second or third day of the menstrual cycle (the first day of the cycle is the day of the onset of menstruation, the appearance of the first spotting). It is at this time that you can assess the true state of the hormonal background.
• At a later date, the data may be unreliable, since the onset of ovarian activity may introduce individual characteristics.
• Typically tested for the following hormones: FSH, LH, estradiol, testosterone, DHEA-S, TSH, T4, prolactin.
• A blood test for progesterone is not given on this day, as its indicator is informative in the second phase of the cycle, for example, on the 20-24th day of the cycle.
• Blood tests for hormones must be supplemented with ultrasound data and information about the cycle. Remember that hormone tests should only be a confirmation of the diagnosis made by the doctor. After all, there is a possibility of natural fluctuations in hormone levels and laboratory error.
