Pregnancy: first week
Every woman who plans to get pregnant starts preparing herself earlier: she stops using stimulants such as alcohol and nicotine, starts eating more rationally and supplements her daily diet with more valuable ingredients, tries to sleep better and avoid stressful situations. All these elements of everyday life are very important not only for the influence of the conceived child and its development, but also for the pregnancy and the preparation of the body for childbirth. How do I know, however, that this important moment, which is fertilization, took place? Since when does pregnancy count? There are several reasons for this.
How to determine 1 week of pregnancy
As the first day of pregnancy, doctors indicate the first day of the last menstrual period, even if fertilization has not yet taken place. It is impossible to determine the exact, actual day of conception, because sperm survive even a few days in the reproductive tract. However, it is enough for it to happen within a dozen or so days after the beginning of menstruation. For women who have regular cycles of 28 days, ovulation and insemination occurs about 14 days later. As a result, when a woman is 4 weeks pregnant, her baby is about 2 weeks younger. Doctors conventionally define the first day of the last menstrual period as the beginning of the first week of pregnancy.
What does the calculation of 1 week of pregnancy have to do with determining the approximate date of birth?
A pregnant woman who goes to see a gynaecologist for the first time should give the date of her last menstrual period and, above all, her first day. In this way you can not only determine 1 week of pregnancy, but also calculate the approximate date of birth. For regular cycles lasting 28 days, add 7 days and subtract 3 months from the first day of the last menstrual period. If the cycles are longer, add 9 months and 11 days to the number of cycles. However, for cycles shorter than 28 days, you need to add 9 months and 5 days. If the cycles are irregular, the only way to calculate the approximate date of birth is to have an ultrasound before the 15th week of pregnancy. During this calculation, it is important to take into account the 2-week margin of error, since conception takes place within 2 weeks of the first day of the last menstrual period and the specific day of conception cannot be indicated.
Pregnancy symptoms in 1 week
The first week of pregnancy is the time when you may not yet know that you have conceived. However, there are first symptoms that are not cause for concern: irritability and mood swings due to hormonal imbalance, swollen and sensitive breasts, vomiting, constipation, heartburn, fatigue and frequent urine. The last of these symptoms is the effect of a loosened and enlarged uterus, in which a place for the child is created, and thus the bladder is pressed down. In the case of morphology, elevated blood leukocyte levels may also indicate that fertilisation has taken place. The body temperature also increases - by about 6-10 lines - on days when menstruation should normally occur, according to the woman's cycle.
Apart from the classic symptoms that may appear in the first week of pregnancy, there are also those that should disturb the woman and induce her to visit a gynaecologist. These symptoms include: increased nausea and vomiting, abdominal pain, spotting from the reproductive tract and systemic infections and infections in the reproductive tract. Bleeding from the genital tract and extremely intense pain in the lower abdomen should be a serious alarm for the pregnant woman, because symptoms of this kind can be dangerous for the maintenance of pregnancy.
Is that a pregnancy?
In the case of women who do not have classic symptoms of the beginning of pregnancy or who are not identified with a new, different condition, it is difficult to determine whether fertilization took place. Especially in the first week of pregnancy it can be difficult to determine, so it is worthwhile to observe your body well, the changes that occur in the body and possibly perform a pregnancy test. To obtain a reliable result, it should be done not earlier than 7-10 days after the last intercourse, i.e. during the time when fertilization may occur. Women who are planning a pregnancy and are not yet in a position to determine whether or not fertilisation has already taken place should treat their bodies as if they had already done so. Thanks to this you can avoid surprises, and the woman from the very beginning will be even better prepared for this special period, which is pregnancy.
