Actually, you can get pregnant any day: before a period, after a period, and even during a period. You are able to get pregnant during any unprotected sexual intercourse, in spite of your “time of the month”. So, yes, the answer to the question: can you get pregnant a week before your period? – is positive. Especially if you didn’t use any contraception and your period is an irregular one. It can depend on the woman’s emotional state, changes of climate, fatigue, a bad state of health, antibiotics intake, an illness (especially catarrhal diseases), and so on.
Why can you get pregnant a week before your period?
Thus, you can’t usually calculate when the exact “a week before a period” comes. 2-3 days before a menstruation and a period itself are in general considered safe, but doctors are sure (and it’s also been proved by many women’s experience) it is, in fact, possible to get pregnant a day before your period or even during it.
The question “can you get pregnant on your period?” doesn’t concern those who don’t have sex during a period. A lot of women show intense sensitivity and increased libido during menstruation, that’s why they can’t abstain from sexual acts at this time. Most gynecologists don’t recommend having sex during a period. They have explained that the female body at the time is weakened, the immunity decreased, so there are far more risks of catching an infection. Inflammation of the appendages or the uterus can also be an unpleasant consequence because during a period the cervix is open, so the risk of some infection getting inside becomes higher. But every situation is unique. If you’ve got a permanent partner and they’re not sick with an infection, you can have sex on a period without fear.
However, if you are not trying to conceive, you need to use contraception because the sperm remains active up to a week after the intercourse, and an egg cell can mature any time (before the middle of the cycle or after it): as a consequence, the ovulation time is shifting. So, can you get pregnant a week before your period? Yes, of course, as well as on a period and after your period. Be especially careful when your menstruation has come earlier or later than usual: you can get pregnant before or during a period.
The chances to get pregnant are very high for those women whose cycle has always been irregular. In theory, gynecologists think that the ovulation comes on the 14th day of the menstrual cycle. But, with irregular periods (it’s also called “an individual cycle”) it’s not so easy to predict it. You should understand that the ovulation will most probably happen earlier or later than the exact middle of your cycle.
There is a higher possibility to get pregnant during the last days of your menstruation. At the beginning of the period, there are little to no chances to conceive because the bleeding is heavy, and such an environment is unfavorable to the sperm. During the last days of the menstruation (irregular periods), the viability of the sperm increases, so there are more chances to get pregnant.
