Chances of getting pregnant right after period ends

I just ended my period. My boyfriend came and then an hour and a half later he we did it wihtout a condom… Could i be pregnant?

It’s possible — there’s no “safe” time in your menstrual cycle to have sex without using birth control. Here’s why: 

Pregnancy can happen when the sperm cells in semen (cum) meet up with one of your eggs. Your ovaries release an egg every month — that’s called ovulation

After sex, sperm can live for up to 5 days in your body waiting for one of these eggs. That means that even if you weren’t ovulating when you had sex, sperm can still meet up with your egg later on. 

Ovulation usually happens about 14 days before your period starts — but everyone’s body is different. You may ovulate earlier or later, depending on the length of your menstrual cycle.

If all this sounds super complicated, that’s because it is. And everyone’s menstrual cycle is a little different, which makes it even MORE complicated. It’s also very common for peoples’ cycles to be irregular, which means your period comes at different times  —  especially when you’re younger. But even if your cycle is regular, it can be hard to know exactly when you’re ovulating and at risk for pregnancy. That’s why it’s so important to use birth control (like condoms, the pill, or an IUD) every time you have sex if you don’t want to get pregnant. 

If you do have unprotected sex, there’s still something you can do to prevent pregnancy afterwards. The morning-after pill (also known as emergency contraception) is a type of birth control that you can take up to 5 days after unprotected sex — but the sooner you take it, the better it works. You can get the morning-after pill at drugstores, pharmacies, and superstores without a prescription from a doctor, no matter your age or gender. Learn more about emergency contraception.

Chances of getting pregnant right after period ends

Getting pregnant just after your period is unlikely, but it’s not impossible.

Getting pregnant just after your period is unlikely, but it’s not impossible.

The chances of getting pregnant are low right after periods compared to a few days or a week in the menstrual cycle:

  • If a woman has sex without using contraception, she may get pregnant at any time during the menstrual cycle, even during or just after the period.
  • There is no absolutely "safe" time of the month when a woman can have sex without contraception and not risk becoming pregnant. However, there are times in the menstrual cycle when women may be most fertile and are most likely to conceive.
  • The fertile days may last for up to 3-5 days after the end of your period. The chances of getting pregnant just after the period depend on how short the menstrual cycle is and how long the period lasts. If periods are long, women may only have a few days left after the period ends before fertile days begin.
  • If the menstrual cycle is short, for example, 22 days, then women could ovulate just days after the period. The longest that sperm can survive in fertile cervical mucus is 5-7 days. So, it may just be possible for women to get pregnant if they ovulate a little earlier than usual.
  • A woman may also get pregnant just after a period if she has an irregular cycle.
Table: Typical menstrual cycles and fertility at each stage
Day of cycleStageFertility
1-7 Menstruation Least fertile stage
8-9 Post-menstruation Possible to conceive
10-14 Days around ovulation Most fertile
15-16 Post-ovulation Possible to conceive
17-28 Thickening of the uterine lining Less fertile, unlikely to conceive

Is it safe to have sex during periods?

Unprotected sex during periods is not advisable. Having unprotected sex, whether oral, anal, or vaginal, always leads to a higher risk of infection owing to skin-to-skin genital contact. While it is often considered safe to have sex during periods, it may lead to a risk of infection due to vaginal discharge. Yeast infection is the most common infection acquired during period sex.

Implementing birth control measures, such as using a condom, may lower your chances of contracting infections and getting pregnant.

There are a few common benefits of having protected sex during periods, such as:

  • Period cramp relief: Since the uterus may be shedding its lining, orgasm may relieve the menstrual cramp. The uterine muscles contract and release over time, leading to less muscle tension. Also, sex leads to the release of endorphins, which helps ease body pains, headaches, and discomfort.
  • Better lubrication: One of the most prominent benefits of having sex during periods is that it allows better lubrication. If the vagina is mostly dry while having sex, the menstrual flow can help to enhance lubrication by acting as a natural lubricant. This contributes to safer and more comfortable sex.

What are the most common early signs and symptoms of pregnancy?

Many of the signs and symptoms differ from person to person.

Below are a few common signs and symptoms that may indicate early pregnancy:

  • Blood or spotting on the panty is one of the early symptoms of pregnancy. The embryo pushes itself into the wall of the uterus (or womb). This causes some light bleeding or spots of blood to appear on the panty.
  • Fatigue or tiredness is a high-ranked symptom among early symptoms of pregnancy. During early pregnancy, levels of the hormone progesterone soar, which makes a patient feel sleepy or tired.
  • Patients might find urinating more often than usual. The amount of blood in the body increases during pregnancy, causing kidneys to process extra fluid that ends up in the bladder.
  • Vulva changes are the early signs and symptoms of pregnancy. Change in the color of the vulva and vagina happens because more blood is needed in that area to build the tissue for pregnancy.
  • Breast and nipple changes are an early sign of pregnancy. Hormonal changes might make breasts sensitive and sore. Nipples may become larger and darker as the pregnancy progresses. Women may also notice small, goosebumps or pimple-like white areas on their areola, which may be an early sign of pregnancy.
  • Having random food cravings is one of the most common early signs and symptoms of pregnancy. It’s caused by the body's craving for what it needs. For example, some women want combinations like fish and ice cream; this could be because the body is lacking protein and sugar.
  • Missed menstrual cycle or period pain is the most common symptom of early pregnancy. If a woman has missed her period by a week or more, there is a chance that she might be pregnant.

How soon can I take a pregnancy test?

Chances of getting pregnant right after period ends

You can take a pregnancy test on the first day of a missed period.

You may take a pregnancy test as soon as you miss a period or if your period is late.

  • You would know the date of your missed period if your periods are regular.
  • If your periods are irregular, or you do not have periods for some reason, you can do a pregnancy test at least three weeks after having sexual intercourse.

It is recommended to take a pregnancy test as soon as possible if you miss your period or if you think you might be pregnant. Knowing about your pregnancy early helps you plan accordingly and seek the necessary care.

You must read the instructions in your test kit to know about the accuracy of the test and how and when to perform it. Some pregnancy tests claim that they can give results a few days before a missed period. The results of testing this early are often less accurate.

Certain pregnancy tests may detect pregnancy hormones as soon as 10 days after unprotected intercourse. These tests have higher chances of inaccuracy and giving false-positive or false-negative test results.

QUESTION

The first sign of pregnancy is most often: See Answer

How do pregnancy tests work?

Pregnancy tests are a quick and easy means to know whether you are pregnant. Most at-home pregnancy tests work by detecting the levels of the hormone human chorionic gonadotropin (HCG) in your urine.

  • HCG is also known as the pregnancy hormone because the levels of this hormone increase considerably when you get pregnant.
  • This hormone is released when a fertilized egg attaches to the lining of the uterus (the endometrium).
  • Thus, when you pee or dip the test stick into your urine, it detects whether HCG is present in your urine.

Most pregnancy tests can be taken beginning on the first day of your missed period. Because the HCG concentration increases rapidly (doubling every two to three days), taking a test early may not be accurate enough. Refer to the label instructions in your test kit to know the best time to take the test.

  • It is generally advised to take the test first thing in the morning because during this time the urine will have the highest concentration of HCG.
  • Drinking a lot of water before the test may dilute the HCG levels in your urine, increasing the chance of a false-negative test result.

How accurate are home pregnancy tests?

Home pregnancy tests are quite accurate and reliable when you use them correctly. Most of the tests available at drugstores claim that they work 99 out of 100 times. Their accuracy is similar to that of a urine pregnancy test that you get in a doctor’s office or hospital. 

  • Because these tests work by detecting the presence of human chorionic gonadotropin (HCG) hormone in your urine, their accuracy might be lower in early pregnancy or when you have just missed your period.
  • If your pregnancy test comes out negative but you feel that you might be pregnant, repeat the test a week after the date you missed your period.

You may want to visit your healthcare provider if you are not confident about the result of your pregnancy test.
