Chances Of Getting Pregnant
The chances of becoming pregnant vary from person to person and from cycle to cycle.
On average, a 30-year-old persons odds of getting pregnant are about 20% per cycle, assuming they are having unprotected sex.
The odds of becoming pregnant also depend on when a person has sex relative to ovulation. An app-based study of people who were trying to get pregnant found the average chances of pregnancy were as follows:
| Timing of sex relative to ovulation | Average chance of pregnancy |
| the day after ovulation | 8% |
Therefore, people should not rely on when their period is due to decide whether to have sex.
The most crucial factor is ovulation. A period indicates the beginning of a new cycle, but it reveals little about when a person might ovulate.
Why Is There A Low Risk Of Pregnancy While A Woman Is On Her Period
Firstly, most couples prefer to abstain from sexual intercourse while a woman is on her period. This is mainly because intercourse is messier at this time. Women also may find sex less interesting at this phase and energy levels are normally very low. In most cases, if the couple does have unprotected sexual intercourse, it does not lead to pregnancy since the ovulation happens several days later.
How Can You Detect Fertile Days
Temperature rise
After ovulation, your basal body temperature increases by 0.51.0°F . While this temperature rise is usually too small to notice, you can detect it with an accurate thermometer.
LH surge
As you approach ovulation, your body will produce increasing amounts of estrogen. The high estrogen levels in your body will trigger an increase in luteinizing hormone . This LH surge will cause the release of mature eggs from your ovary, which is ovulation. Since ovulation usually occurs about 24-48 hours following the LH surge, this hormone is often an excellent predictor of peak fertility.
Changes in saliva
Research has shown that a womans saliva also changes considerably depending on the bodys estrogen level. During your monthly cycle, you will experience a large increase in estrogen a couple of days before ovulation and another minor increase a few days before your period is due.
If you experience irregular menstrual cycles, tracking ovulation could be helpful using several different tools.
Cycle chart
If your cycle is irregular, try tracking it on your calendar for a few reasons. You might notice a pattern, and you can share the information from your tracking efforts with your gynecologist or fertility specialist.

Women with short menstrual cycles have a higher than normal risk of getting pregnant during periods. In cases where women have a menstrual cycle of 21 to 25 days, ovulation occurs a few days after periods. Sperm can live inside the female body for up to 5 days. Thus if you were to have sexual intercourse towards the end of your periods and ovulate a few days after this, there is a high chance you may get pregnant.
How Can You Tell If You Are Ovulating
Frustratingly, theres no way of knowing for sure when you are ovulating. However, your body does give clues as to when ovulation might be occurring, and there are tools that you can use to gain greater clarity.
Ovulation kits that measure levels of luteinising hormone in urine often give a good indication of when you are likely to be ovulating, says Yasmin. Ovulation occurs after an LH surge, so whilst a positive test can suggest ovulation, its worth bearing in mind that it might not be 100% accurate.
Other signs you might be ovulating include changes in your body temperature or discharge , and tender breasts.
Tracking your menstrual cycle using an app, such as Clue, will help to give you an idea of when youre most likely to ovulate.

How Can A Woman Get Pregnant On Her Period
Its easy to mistake vaginal bleeding for the beginning of a period. Its possible you could bleed during ovulation when youre most fertile. This could easily be mistaken for a period. Having unprotected sex at this time dramatically increases your chances of becoming pregnant.
For the average woman, the ovulation cycle is somewhere between 28 and 30 days. This means that if you have sex while on your period, you wont likely ovulate until several days later.
But women with a shorter cycle wouldnt have the same amount of time between having their periods and ovulating.
Another consideration is that a mans sperm can live inside a woman for up to 72 hours after ejaculation. Toward the end of your period, your chances of becoming pregnant will increase.
If youre curious about your ovulation patterns, you can track the number of days between your periods. This includes when you start your period, and then when you start your period again.
Over several months, you can identify a pattern to determine roughly when your ovulation cycle occurs.
Tampons And Pads Arent Your Only Choices
You have more options to help you manage that time of the month.
A menstrual cup is a flexible cup that fits inside your vagina and collects blood during your period. Period panties are super-absorbent, and you can wear them on their own on your lighter days or with a tampon during heavier times. Reusable cloth pads can be washed and worn again.
These products can be cost-savers, since you can reuse them, and they also create less waste. In some cases, they give you more time between changes. For example, you need to change a tampon every 4 to 8 hours, but you may be able to go up to 12 hours with a menstrual cup before you empty it.
There are pros and cons to all these options, just as there are with tampons and pads. But you can find one that works best for you with some trial and error.

What Are The Possible Side Effects
The biggest downside to having sex during your period is the mess. Blood can get on you, your partner, and the sheets, especially if you have a heavy flow. Aside from dirtying the bed, bleeding may make you feel self-conscious. Anxiety over making a mess can take some or all of the fun out of sex.
Another worry about having sex during your period is the risk of passing on a sexually transmitted infection like HIV or hepatitis. These viruses live in blood, and they can spread through contact with infected menstrual blood. Using condoms every time you have sex can reduce your risk of spreading or catching an STI.
If you plan to have sex during your period and youre wearing a tampon, you need to remove it beforehand. A forgotten tampon can get pushed so far up into your vagina during sex that youll need to see a doctor to have it removed.
While Youre On Your Period
As any woman with a calendar and a bunch of best friends will tell you, the amount of days each woman spends menstruating can vary a lot.
Your menstrual flow may start to diminish and lighten in color, or turn brown towards the end of your cycle. It feels and looks like youre still menstruating, but your body is already gearing up for your next fertile time.
If you have sex towards the end of your period, you may actually be getting close to your fertile window, especially if you have a short cycle. Lets take a look at the math.
Say you ovulate early, about six days after your period starts. You have sex on the third day of your period. The sperm have no egg to fertilize, but theyre also in no hurry to die so they hang out, doin what sperm do.
A few days later, while theyre still swimming around, you ovulate and theyre drawn to that egg like a fish to water. One gets through, and there you have it fertilization has occurred as a result of period sex.

Chances Of Getting Pregnant On Your Period
In essence, menstruation is the monthly shedding of the endometrium, the inner membrane of the uterus. Menstruation lasts between three and seven days for most women. By the third day, levels of progesterone and estrogen are rising and working to rebuild your endometrium. Around day four, follicle ripening begins to go on the uptick, meaning the ovaries will start preparing eggs for release.
Unless you’re a very early ovulator , there’s little chance your man’s sperm will actually have any eggs to work with during this phase of your cycle.
Your chances of conceiving: Almost zero. It’s not detrimental to have intercourse, though, and some women see menstruation as a breather from the rigors of frequent procreation-oriented sex.
What Are The Chances I Can Get Pregnant On My Period
The chances of getting pregnant if you have sex during your period are very low. However, if youve had unprotected sex, it is still possible to get pregnant during your period.
To understand how this can happen, you need to know how your menstrual cycle works.
- Your cycle starts on the first day of your period and lasts until the first day of your next period.
- About 10 to 16 days before the start of your next period, you will ovulate, which is when one of your ovaries releases an egg.
- Once youve ovulated, you enter the Luteal phase, when the now empty follicle develops the corpus luteum, which produces the hormone progesterone.
- The lining on your uterus thickens in preparation for a fertilised egg to implant.
- If you have not conceived, then the egg passes into the uterus, hormone levels drop, and the womb lining sheds as you begin your next period.

You are at your most fertile around the time you ovulate. Although the egg lives only for 12 to 24 hours after being released, you can get pregnant even if you have sex days before you ovulate as sperm can live up to five days in your body.
So how likely are you to get pregnant during your period? Well, it depends on a few factors like:
- whether you used contraception or not
- the length of your menstrual cycle
- the length of your period
- when you had sex

Ive Been Using Contraception Will This Affect My Cycle
This depends on what type of contraception youve been using. If youve been taking the pill, your period may be irregular when you first come off it, so try to give yourself up to 3 months for your natural menstrual cycle to get back to its normal routine.
The first period after stopping the pill is known as a withdrawal bleed. The next one after this is your first natural period.
The contraceptive injection can also affect your cycle. Your periods may change and become irregular, heavier, shorter, lighter or stop altogether. This can carry on for some months after you stop the injections.
If you use the contraceptive implant your fertility will return to normal as soon as it is taken out.
Fertility Awareness As A Method Of Birth Control
All birth control methods can fail, even those with the highest effectiveness rate like intrauterine devices or tubal ligation. People should understand how well each option works prior to deciding upon a method of contraception.
When using fertility awareness as a method of birth control, fewer than five out of 100 women will become pregnant during the first year of perfect use. That being said, this method of birth control is very difficult to do without error.
When tracking your cycle, the first day should be when you begin bleeding. For most women, ovulationthe release of the egg from the ovariesoccurs around day 14. Some women may bleed for up to 10 days. Therefore, they may become fertile only four days after their period ends, Harper said. Some women even have earlier ovulations and some have later ovulations.

How To Calculate Ovulation Date
Ovulation usually takes place 14 days before the start of a period. The number of days between the end of your period and date of ovulation may differ but the spacing between ovulation and the start of your period always stays the same. Hence, to calculate your ovulation date, work backwards from the start of your period. This will tell you when you are most fertile.
Pms Is Still A Mystery
Itâs 1 or 2 weeks before your period starts, and here come the breakouts, sluggishness, cravings, bloating, and mood swings. Sound familiar? Every woman is different, but for many, PMS is a fact of life.
But doctors donât know exactly why that is. It seems to be a mix of hormone changes during your menstrual cycle, chemical changes in the brain, and other emotional issues you might have, such as depression, that can make PMS worse.
Whatâs more, once you get your period, the rollercoaster may continue. One study found that period-related pains such as cramps, bloating, backaches, and headaches can cloud your thinking, because the pain may make it harder for you to focus on the tasks at hand. Not that you canât still do them — you can. It may just feel like it takes more work.
Lifestyle changes are usually the best way to take control of PMS. Aim to get about 30 minutes of exercise most days of the week, get 8 hours of shut-eye per night, and donât smoke. Your diet makes a difference, too, so fill up on fruits, veggies, and whole grains while you limit salt as well as sugar, caffeine, and alcohol.
Let your doctor know if PMS keeps you from doing what you normally do, or if you have symptoms of depression or anxiety. You may have a more serious condition called premenstrual dysphoric disorder that needs medical attention.
