Can a girl be pregnant 2-3 days before her menses starts?

Question

My GF and we went into the course today, n i was not using rubbers and ejaculated in her. Her periods are probable to start today only or tomorrow. Now, can she be preg?

Answer 1

A girl can get pregnant anytime even when she is on her period even though it is unlikely. The highest risk of your gf becoming pregnant is 2 wks after her period..but she could have gotten pregnant this time...my advice be careful...it happens and I am speaking from experience. If your girl gets her period get her to take a pregnancy test after she is off of it just to be safe. You can still have your period while your pregnant...I did.

Answer 2

most likely your gf is not pregnant. though when it comes to a female's cycle, anything can happen. if she is getting her period in a day or two, likely she has ovulated about 14 days ago, which puts her at the least likely to get pregnant.

Answer 3

Yes she can!

Before pregnancy begins, a female oocyte (egg) must join, by male spermatozoon in a process referred to in medicine as "fertilisation", or commonly (though perhaps inaccurately) as "conception." In most cases, this occurs through the act of sexual intercourse, in which a man ejaculates inside a woman, thus releasing his sperm. Though pregnancy begins at implantation, it is often convenient to date from the first day of a woman's last menstrual period. This is used to calculate the Estimated Date of Delivery (EDD).

Traditionally (according to Naegele's rule, which is used to calculate the estimated date of delivery, or EDD), a human pregnancy is considered to last approximately 40 weeks (280 days) from the last menstrual period (LMP), or 37 weeks (259 days) from the date of fertilization. However, a pregnancy is considered to have reached term between 37 and 43 weeks from the beginning of the last menstruation. Babies born before the 37 week mark are considered premature, while babies born after the 43 week mark are considered postmature.

According to the Merck Medical Manual, the norm for human pregnancy is approximately 266 days from the date of fertilization. This is 38 weeks, or approximately 8 Gregorian months and 22.5 days, or 9.0 lunar months). Counting from the beginning of the woman's last menstrual cycle, the norm is 40 weeks (the basis for Naegele's rule). Also, less than 10% of births occur on the due date, 50% of births are within a week of the due date, and almost 90% within two weeks. But it is not clear whether this refers to the due date calculated from an early sonograph or from the last menstruation (see further down).

Though these are the averages, the actual length pregnancy depends on various factors. For example, the first pregnancy tends to last longer than subsequent pregnancies.

An accurate date of fertilization is important, because it is used in calculating the results of various prenatal tests (for example, in the triple test). A decision may be made to induce labour if a baby is perceived to be overdue. Due dates are only a rough estimate, and the process of accurately dating a pregnancy is complicated by the fact that not all women have 28 day menstrual cycles, or ovulate on the 14th day following their last menstrual period. Approximately 3.6% of all women deliver on the due date predicted by LMP, and 4.7% give birth on the day predicted by ultrasound.

The beginning of pregnancy may be detected in a number of ways, including various pregnancy tests which detect hormones generated by the newly-formed placenta. Clinical blood and urine tests can detect pregnancy soon after implantation, which is as early as 6-8 days after fertilization. Home pregnancy tests are personal urine tests, which normally cannot detect a pregnancy until at least 12-15 days after fertilization. Both clinical and home tests can only detect the state of pregnancy, and cannot detect its age.

In the post-implantation phase, the blastocyst secretes a hormone named human chorionic gonadotropin which in turn, stimulates the corpus luteum in the woman's ovary to continue producing progesterone. This acts to maintain the lining of the uterus so that the embryo will continue to be nourished. The glands in the lining of the uterus will swell in response to the blastocyst, and capillaries will be stimulated to grow in that region. This allows the blastocyst to receive vital nutrients from the woman. Pregnancy tests detect the presence of human chorionic gonadotropin.

An early ultrasound can determine the age of the pregnancy fairly accurately.

In practice, doctors typically express the age of a pregnancy (i.e. an "age" for an embryo) in terms of "menstrual date" based on the first day of a woman's last menstrual period, as the woman reports it. Unless a woman's recent sexual activity has been limited, the exact date of fertilization is unknown. Absent symptoms such as morning sickness, often the only visible sign of a pregnancy is an interruption of her normal monthly menstruation cycle, (i.e. a "late period"). Hence, the "menstrual date" is simply a common educated estimate for the age of a fetus, which is an average of two weeks later than the first day of the woman's last menstrual period. (The margin of error is 0 to 30 days after last menstruation, hence a 14 day average.) The term "conception date" may sometimes be used when that date is more certain, though even medical professionals can be imprecise with their use of the two distinct terms. The due date can be calculated by using Naegele's rule.


An ultrasound of a developing fetus.There are likewise finer distinctions between the concepts of fertilization and the actual state of pregnancy, which starts with implantation. In a normal pregnancy, the fertilization of the egg usually will have occurred in the Fallopian tubes or in the uterus. (Often, an egg may become fertilized yet fail to become implanted in the uterus.) If the pregnancy is the result of in-vitro fertilization, the fertilization will have occurred in a Petri dish, after which pregnancy begins when one or more zygotes implant after being transferred by a physician in the woman's uterus.

In the context of political debates regarding a proper definition of life, the terminology of pregnancy can be confusing. Because precise assessment of a pregnancy as being at the "embryo" or "fetus" stage is usually undeterminable, the terms (though more clinically precise) are less commonly used than terms like "baby" or "child." The medically and politically neutral term which remains is simply "pregnancy," though this can be problematic as it only refers indirectly to the embryo or fetus. In the context of personal treatment, bedside manner generally dictates that doctors make sparse use of clinical language like "fetus" and "embryo," and instead simply refer to the developing child as a "baby", though this is not medically accurate.
