Your questions to the doctor
As much as needs
Question: How often can a pelvic ultrasound be done during pregnancy without harm to health? The doctor already prescribes my fourth examination in a month, and I heard that although this is not an X-ray, it is also not such a harmless procedure.
Answer: There is no strict regulation determining how many times you can do an ultrasound during pregnancy, and how much is harmful. There are certain deadlines for performing an ultrasound with a normal pregnancy, but if problems arise and without an ultrasound it is impossible to assess the situation and decide on further treatment tactics, then the amount of ultrasound 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 an ultrasound scan, 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. Just doing an ultrasound once again during pregnancy is not worth it.
IN: Is it possible to artificially cause a delay in menstruation? I take a hormonal contraceptive, can I stop taking it not on the 21st day, but 2-3 days later if necessary?
ABOUT: Yes, it’s possible, but only if you are taking a monophasic drug (there is no “tri-” prefix in its name). Modern hormonal contraceptive regimens suggest a longer administration of the drug without a break for menstruation. The most common scheme is now 63 + 7, that is, you take three packs in a row without seven-day breaks (21 + 21 + 21 = 63) and only then take a break of seven days, so you can easily cancel your periods and transfer them to any time convenient for you without harm to your health.
The birth of the corpus luteum
IN: Around the middle of the cycle, I begin to have pains in the mammary glands and in the lower abdomen, after a couple of days everything goes away. What does it mean?
ABOUT: This is the norm. At the beginning of each menstrual cycle, a follicle begins to grow in your ovary (a “bubble” in which the egg ripens). By the middle of the cycle (12-14th day with a 26-28-day cycle), this follicle bursts (a process called ovulation) and the egg leaves it. In place of the bursting follicle, a yellow body forms. The ovulation process is accompanied by a sharp change in the concentration of certain hormones. Some women do not feel this, nor do they feel pain when the follicle ruptures, while others feel both ovulation and hormonal fluctuations.
Simple tips: Rules Analyzes
A question that interests many: on what day of the cycle do you need to take hormone tests and which hormones?
• A blood test for sex hormones is given on the second or third day of the menstrual cycle (the first day of the cycle is the day the menstruation begins, the appearance of the first spotting). It is at this time that you can evaluate the true state of the hormonal background. • At a later date, the data may be unreliable, as the activity of the ovaries that has begun may introduce individual characteristics. • As a rule, tests for the following hormones are performed: FSH, LH, estradiol, testosterone, DHEA -C, TSH, T4, prolactin. • A blood test for progesterone is not given on this day, since its indicator is informative in the second phase of the cycle, for example, on the 20th to 24th day of the cycle. • Blood tests for hormones must be supplemented ultrasound data and cycle information. Remember that hormone tests should only be a confirmation of the diagnosis made by your doctor. After all, there is a chance of natural fluctuations in the level of hormones and a laboratory error.
