Can You Get Pregnant Right Before Or After Your Period
Doctors generally agree that people are not likely to get pregnant in the days leading up to their period. This is especially true if their periods are regular and they have a 28-day menstrual cycle.
However, given the fluid nature of the fertile window, people who do not want to become pregnant should still use contraception at this time.
Sperm cells can only fertilize an egg within a 24-hour window after ovulation. If a person knows when they have ovulated and counts w days from ovulation, they should no longer be able to get pregnant before their next period.
It is, however, possible for a person to get pregnant immediately after their period. This is because sperm can still fertilize eggs for 35 days after sexual intercourse.
If a person with a short cycle has sexual intercourse right after their period and happens to ovulate early, they may ovulate quickly enough for the egg to connect with sperm cells.
Top Reasons Your Vaginal Bleeding May Not Be A Period
One of the biggest margins for error while using fertility awareness as a method of birth control comes from a misidentified period. Not all vaginal bleeding is a period. A woman may bleed from a hormonal imbalance, cervical lesion, recent trauma and even pregnancy.
If you are tracking your menstrual cycle and the bleeding is consistent in terms of heaviness, color and timing, then you can likely count on it being your period, Harper said. However, there are many women that find it difficult to track their period because irregular bleeding can be due to illness or another underlying cause.
If you are having difficulty or need help starting, talk with your OB-GYN or primary care provider.
Estimation Of Due Date
Due date estimation basically follows two steps:
- Determination of which time point is to be used as origin for gestational age, as described in the section above.
- Adding the estimated gestational age at childbirth to the above time point. Childbirth on average occurs at a gestational age of 280 days , which is therefore often used as a standard estimation for individual pregnancies. However, alternative durations as well as more individualized methods have also been suggested.
Naegele’s rule is a standard way of calculating the due date for a pregnancy when assuming a gestational age of 280 days at childbirth. The rule estimates the expected date of delivery by adding a year, subtracting three months, and adding seven days to the origin of gestational age. Alternatively there are mobile apps, which essentially always give consistent estimations compared to each other and correct for leap year, while pregnancy wheels made of paper can differ from each other by 7 days and generally do not correct for leap year.
Furthermore, actual childbirth has only a certain probability of occurring within the limits of the estimated due date. A study of singleton live births came to the result that childbirth has a standard deviation of 14 days when gestational age is estimated by first trimester ultrasound, and 16 days when estimated directly by last menstrual period.

Clomid is often prescribed to women with polycystic ovary syndrome, or PCOS, which is a syndrome that can cause irregular or absent ovulation.
Not everyone will respond to this medication. Women with primary ovarian insufficiency, or early menopause, and women with absent ovulation due to low body weight or hypothalamic amenorrhea are most likely to not ovulate when taking Clomid. Women with these conditions may need more intensive infertility treatment.
For women who are appropriately treated with Clomid, there are many benefits:

Im Pregnant But Have Some Bleeding Is This My Period
Implantation bleeding sometimes happens pregnant women around the time theto period would have been due. Implantation is when the developing embryo plants itself in the wall of your womb. An implantation bleed is very light bleeding that is usually pinkish and sometimes brown. Not everyone will have an implantation bleed.
Its common to have light bleeding or spotting without pain before 12 weeks. This isnt often serious, but you should contact your doctor, midwife or Early Pregnancy Unit immediately to be checked, just in case.
Can You Get Pregnant On Your Period
If you are wondering whether you can get pregnant while on your period, the answer is not as simple as you think.

Why You Might Experience A Period During Your First Trimester
Though people stop getting their period during pregnancy, its possible that they may still experience some bleeding. This bleeding does not necessarily indicate an underlying issue, but its important to understand the cause of it and whether its time to see a health care provider.
Bleeding tends to occur more often during the first trimester of pregnancy than the second or third. Estimates suggest that about 25 to 30 percent of pregnant people experience spotting at some point during their first trimester. There are a number of reasons for this bleeding.
Implantation bleeding: This refers to the light spotting that occurs about 10 to 14 days after conception, around the time when your period is due. Many people havent yet taken a pregnancy test at this point, so its easy to mistake the spotting for a period. This bleeding is lighter than a normal period, however, and only lasts for a couple of days. It occurs due to the implantation of the fertilized egg into the uterine lining.
Cervical changes: Spotting can occur shortly after you get pregnant due to cervical changes, and particularly after having sexual intercourse. As long as no infection is present, theres no need to be concerned about this.
Other causes: Heavier bleeding that more closely resembles a period during the first trimester of pregnancy can indicate something more serious, including:
- Back pain
- Uncontrollable vomiting and nausea
Can You Get Pregnant On The First Day Of Your Period
It’s possible though not very likely for you to get pregnant on the first day of your period, especially if you have a regular, 28-day cycle.
If you have an irregular or a shorter menstrual cycle, however, ovulation might occur much closer to day one of your period, which would cause you to get pregnant on the first day.

Ovulation And The Fertility Window
Can you get pregnant on your period? Menstruation sex can lead to conception, though research conducted by the National Institute of Environmental Health Sciences found that there are typically six days a month when a woman may become pregnant. This period, known as the fertility window, occurs during ovulation.
Ovulation is the stage during which a womans body releases the egg for the purpose of fertilization. A womans fertility window may occur between days 10 and 17 according to a study published by the British Journal of Management. During this window, a woman has a minimum of 10% chance of pregnancy without the use of birth control, according to the same study.
Can A Girl Get Pregnant If She Has Sex During Her Period
Can a girl get pregnant if she has sex during her period? Jamie*
Yes, a girl can get pregnant during her period. This might happen when:
- A girl has bleeding that she thinks is a period, but it’s bleeding from . Ovulation is the monthly release of an egg from a girls ovaries. It is the time when she is most likely to get pregnant if she has sex.
- Ovulation happens before the bleeding from a girl’s period has stopped.
- Ovulation happens within a few days after a girl’s period is over. Sperm can fertilize an egg for 3 days. So if a girl has sex on the last day of her period and ovulates in the next few days, the sperm may still fertilize the egg.
Having unprotected sex at any time is risky. Along with the risk of getting pregnant, you could also get an STD, such as chlamydia, genital warts, or HIV. The only way to completely prevent pregnancy and STDs is abstinence .
If you do have sex, use a condom every time to protect against unplanned pregnancy and STDs. For added protection, many couples use condoms along with another method of birth control, like birth control pills or an IUD. Talk to your doctor about the best type of birth control for you.

Bleeding Later In Pregnancy: Why It Happens
Weve already discussed why it isnt possible to have a period during pregnancy, and why some people may experience light bleeding or spotting during their first trimester. Bleeding during the second and third trimesters is possible, though not common, and it may be an indicator that something else is going on. If you experience bleeding later in your pregnancy, its important to see your health care provider.
Potential reasons for mid- or late-term pregnancy bleeding include:
Can You Get Pregnant On Your Period If You Have An Irregular Cycle
Yes. If you have an irregular period, it can be harder to predict when youll be ovulating and that could cause you to get pregnant accidentally, since it can be harder to avoid having sex close to that time.
Here are a few types of irregular menstrual cycles, and how it’s still possible to get pregnant:
- You have a short cycle. Some women have cycles as short as 21 days and still ovulate, which means they dont have as much time between when they finish menstruating and when they next ovulate. And since sperm can live in your reproductive tract for a few days, if you happened to have sex during your period and then ovulated the following cycles egg two to three days later, that egg could encounter viable sperm. And you know what that means.
- Your periods last a long time. While your body is slowly shedding that uterine lining, the clock is ticking on ovulation and your next egg shows up while youre still bleeding from the previous months egg. So youre already fertile again which means you can get pregnant on your period.
- You have breakthrough bleeding, or spotting, when you ovulate. Especially if you have light or irregular periods, it would be easy to mistake this bleeding for a true period even though its happening when youre actually most fertile, since youve just ovulated.
Sometimes, however, an irregular period can be a sign that you’re not ovulating at all, which is one cause of infertility.

When To See Your Health Care Provider
Because it isnt possible to get your period while pregnant, its important to be mindful of any bleeding you do experience during this time. While light bleeding or spotting during the first trimester is usually normal, bleeding that is accompanied by other symptoms may indicate something more serious, and its important to see a health care provider immediately. These symptoms include:
- Cramping and pain
- Passing clots or heavy bleeding
- Severe pain in your pelvis and stomach
Its important to visit your health care provider if your bleeding is bright red in color and is heavy enough to soak through a pad. Pelvic pain and vaginal bleeding in the early stages of pregnancy may indicate an ectopic pregnancy. If you suspect this, see your health care provider as soon as possible.
Theres a lot of discussion surrounding pregnancy and periods, and we want to clear things up. Can you have a period and be pregnant? No. Since your period stops after your body starts producing hCG also known as the pregnancy hormone it isnt possible to experience a true period during pregnancy.
During the early stages of pregnancy, however, some people experience spotting or light bleeding and its usually normal. This bleeding is called implantation bleeding, and it happens when the fertilized egg implants in the uterine lining.

Development Of Embryo And Fetus
The sperm and the egg cell, which has been released from one of the female’s two ovaries, unite in one of the two Fallopian tubes. The fertilized egg, known as a zygote, then moves toward the uterus, a journey that can take up to a week to complete. Cell division begins approximately 24 to 36 hours after the female and male cells unite. Cell division continues at a rapid rate and the cells then develop into what is known as a blastocyst. The blastocyst arrives at the uterus and attaches to the uterine wall, a process known as implantation.
The development of the mass of cells that will become the infant is called embryogenesis during the first approximately ten weeks of gestation. During this time, cells begin to differentiate into the various body systems. The basic outlines of the organ, body, and nervous systems are established. By the end of the embryonic stage, the beginnings of features such as fingers, eyes, mouth, and ears become visible. Also during this time, there is development of structures important to the support of the embryo, including the placenta and umbilical cord. The placenta connects the developing embryo to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother’s blood supply. The umbilical cord is the connecting cord from the embryo or fetus to the placenta.
