There is a possibility of pregnancy.
It is sometimes said that "even if you ejaculate during your period, it will be expelled with your menstrual blood, so you will not get pregnant," but this is actually a big mistake.
For those whose ovulation cycles are not stable, it is possible for ovulation to occur immediately after menstruation and pregnancy to occur.
In addition, sperm usually survives for two to three days.
It is also possible that fertilisation may occur by sperm that has survived after menstruation has ended. Those who do not wish to become pregnant should use contraception.
A higher risk of infection
The vaginal lining during menstruation is in a delicate state, as the endometrium is in the process of peeling off, so even the slightest stimulation can easily cause damage.
Normally, the vagina has a self-cleaning mechanism that prevents infection from viruses and bacteria with low infectivity.
However, during menstruation, the immune system is weakened, making it easier for viruses and bacteria to invade.
Sex during menstruation increases the risk of chlamydia, papillomavirus, gonorrhea, and other viruses transmitted through wounds.
Increased risk of endometriosis
Sex during menstruation can cause menstrual blood to flow back into the uterus when it is supposed to be expelled.
When menstrual blood flows back into the uterus, there is a risk of carrying bacteria and viruses into the uterus.
As viruses and bacteria increase in the uterus, the risk of endometriosis increases.
Endometriosis is a disease in which the endometrium, which normally covers the inner wall of the uterus, forms in areas outside the uterine lumen. It can cause pain, inflammation, and adhesions, and if left untreated, can lead to infertility.
It is best to inform him ahead of time.
It is best to tell your boyfriend that you have your period the day before the date rather than the day of the date. If you suddenly tell him on the day of the date, he may be confused and not know what to do. By telling him in advance, it will be easier for him to change the date plan according to his condition.
If you are going to tell him on the day of the date, do it right after you meet him.
If you have your period on the day of your date with your boyfriend, it is best to tell him immediately after meeting him. The worst timing is telling him when you are in a good mood on the date.
If you tell him you are menstruating when you are about to have sex with him, he will be less excited. Also, refusing right before the date may lead to a misunderstanding that "Is this a lie to refuse sex?" If you tell him you are menstruating, it may cause a misunderstanding.
How to casually tell him you are menstruating.
Explain to him, in a roundabout way, that you are not feeling well.
If you have been dating for a long time, you may feel uncomfortable telling your boyfriend that you are menstruating. In such a case, you can casually tell him that you are not feeling well without mentioning the word "menstruation."
If you say, "My stomach hurts a little today," or "My stomach is heavy and I don't feel well," he may be able to tell that you are on your period. He may be able to guess if you are menstruating or not.
Inform him of your menstrual cycle.
If you are embarrassed to tell your boyfriend that you have your period every month, it is a good idea to tell him your menstrual cycle, such as "I get my period around the end of the month."
If you let him know your general menstrual cycle, he will be able to guess that it is time for your period even if you postpone the date when you get your period. This will also make it easier to schedule a date!
If you must have sex during menstruation, avoid the first three days of menstruation, use contraception even during menstruation, and use shallow penetration to reduce the backflow of menstrual blood.
Also, the use of lotion is recommended to prevent friction damage. Avoid having sex in the bathroom, as it is easier for germs to enter the body.
Oral sex with a condom is also recommended to reduce the risk of infection.
Another method is to adjust your menstrual period in advance with a pill so that your date does not conflict with your period.
It is best to rest during menstruation. Take it easy and enjoy your date with your partner!
