Which is the Best Time to get Pregnant after Periods?
Periods and pregnancy
Anatomical, biological and sexual knowledge girls receive from school courses in anatomy and thanks to the stories of older comrades and peers. And among the inhabitants, the theory that menstruation can be used as a means of contraception is widespread. That is, before the menstrual cycle and on the first day - while the bloody discharge is insignificant - or at the end of the cycle, having sex, you do not need to protect yourself.
And then, when an unwanted pregnancy comes, they wonder how this could happen? So is it possible to get pregnant on the first day after your period or immediately after it?
What's going on in the body during menstruation?
In the first days of the menstrual cycle, follicles begin to increase in the ovary under the influence of follicle-stimulating hormone - their number can vary from 8 to 12 - and after a few days 2 of them reach large sizes. These follicles are called dominant - the rest are absorbed.
As soon as the dominant follicles increase over 20 mm, they mature and their membranes become thinner. On the day of ovulation - in healthy women, it happens in the middle of the cycle - the follicles leave the ovaries into the lumen of the fallopian tubes and there - if intercourse took place at that time - they meet with sperm. Bloody discharge during menstruation is a rejection of the functional layer uterine endometrium . The endometrium consists of 2 layers: basal - internal, and functional - external.
If pregnancy has not occurred, the functional layer becomes obsolete and is rejected. Basal during a new cycle stimulates the formation of a new functional. It is fully formed in the 2nd phase of the menstrual cycle - vessels, connecting elements and glands grow in it.
Under the influence of the corpus luteum hormone - progesterone - functional transformations occur in the endometrium. By 2/3 months of age, optimal conditions are created for the attachment of the embryo, a reserve of nutrients is provided. Pregnancy did not take place - menstrual bleeding begins.
If you take the average menstrual cycle of 28 days in a healthy woman, you can see how the thickness of the endometrium changes during it:
- on the last day of the cycle, thickness 6 mm;
- after, by day 8 - up to 8-10mm;
- 10-14 - up to 14 mm;
- up to 18 - from 10 mm to 16;
- by the 23rd day, the optimal thickness of the endometrium is about 14-18 mm;
- and by the 28th day it already decreases somewhat, dries up - albeit slightly, by 1mm - and menstruation begins.
Since for the embryo implantation, an endometrial layer of at least 10 mm is required, then to the question: is it possible to get pregnant on the first day of menstruation, in the case of a healthy woman, the answer is unequivocal - no!
The duration and cyclicity of the menstrual cycle depends on the production of female hormones by the body - progesterone and estrogen. And it depends on many factors - internal and external. Disease, climate change, dietary changes and stressful situations can affect the menstrual cycle.
Its changes shift the time of menstruation, speed up or slow down the process, reduce or increase the amount of rejected endometrium.
Therefore, it is impossible to give an exact answer to the question about the possibility of getting pregnant after the first day of menstruation, if the menstrual cycle fails. Of course, in the first days of menstruation, menstruation is abundant, and sperm, if intercourse takes place at this time, are washed off, but rarely does anyone enter into a relationship these days. Therefore, there is still a chance for a fertilized egg that lurks in the fallopian tube.
Irregular menstrual cycle
The menstrual cycle, and hence ovulation, is shifted under the influence of the following factors:
- inflammatory and infectious diseases - gynecological and general;
- due to abortion or abortion;
- gynecological operations;
- when entering menopause;
- due to irregular sex life;
- if a woman has an irregular menstrual cycle is an individual feature.
In this case, the calendar method cannot be protected. Do not rely on the calendar and
when changing seasons or time zones, after stress.
The regularity of taking oral contraceptives affects the time of ovulation. If a woman periodically forgets to take pills, then the maturation of the follicle and its exit into the fallopian tube cannot be predicted. There is also a very interesting phenomenon - spontaneous ovulation. Scientists have not yet studied its causes and the mechanism itself.
In each of the ovaries, the ovaries mature by an egg - only one earlier, and the other later, and both go out into the fallopian tube. One of them is subsequently rejected along with the unnecessary endometrium, and the other meets a sperm and is introduced into the endometrium, albeit not completely prepared, but capable of accepting a guest - since during this time he has already managed to reach thickness 5-7 cm.
You can get pregnant in the first days of your period under the following circumstances:
- Short mensnormal cycle - 21-23 days - sexual intercourse on those days when blood loss decreases - by 3-4 days. The probability of pregnancy with early ovulation is as high as possible;
- Sexual intercourse was before the very menstrual period or on the first day, the cycle is short - up to 3 days;
- Regardless of the length of the menstrual cycle, early ovulation occurred due to hormonal disruptions.
You might not even guess about pregnancy, since the release of blood in the 1st trimester is not even surprising. Menstruation during pregnancy is quite common, especially while the body is is determined - whether it needs a pregnancy or not.
Even 10-15 years ago, at a period earlier than 9 weeks, pregnancy was not maintained, it was believed that this is how the viability of the future fetus is determined. Now the views on what is happening have changed, and pregnancy at this time is maintained very successfully.
On average, the days from the start of the cycle to 11, and a week before the start of the cycle are considered safe. But one could already see how inaccurate this calculation can be.
It is impossible to get pregnant during your period if your body is working like clockwork.
- At 28-35 cycles, which repeats with enviable regularity, ovulation occurs exactly in the middle. Plus or minus 4 days are favorable for conception - the rest of the unwanted pregnancy should not be feared;
- Coitus happened on the day of the strongest discharge - the menstrual cycle is irregular: plus or minus 5 days.
If you reinforce the calendar method by measuring the basal temperature - every morning to insert a thermometer into the rectum and build a graph - then you can still rely on it. Any change in the woman's condition can lead to the fact that the time of ovulation will shift, which will reduce all efforts to avoid unwanted pregnancy to zero. Don't rely on the calendar method. An unhealthy environment and the impact of nervous factors have made women's bodies vulnerable, and even a healthy woman cannot be sure that she ovulates on the day appointed by nature.
There are many ways to protect yourself - from the use of barrier agents to the use of hormone replacement therapy. If there are concerns that these methods will change sensory sensations, you can use special tests - they are now sold in all pharmacies - and first check the possibility of unprotected intercourse. These tests indicate the onset of ovulation.
During menstruation, the cervix is slightly open, the possibility of introducing foreign flora is maximized, the surface of the uterus is an open wound. An unwanted pregnancy is not as bad as the chance of contracting a gynecological disease.
No wonder the main world religions are forbidden to have sexual intercourse during menstruation. Healthy mothers - healthy childrenand, you should never forget about it.
