Can You Take a Pregnancy Test While on Your Period?


One question many women want the answer to is, “Can you take a pregnancy test while on your period?” Well, as most people know, periods are associated with fertility. Before home pregnancy tests existed, the easiest way for a woman to determine whether or not she was pregnant was with the notable absence of monthly bleeding, more commonly known as a late period. However, periods can also be tricky. In very early stages of pregnancy, a woman can still get her period. If the level of hormones that control menstruation are too low to stop it. Usually, a period that occurs in the early stages of pregnancy will be way less heavy than you are accustomed to.Baby characters cookies

A small percentage of women may even experience a menstrual cycle throughout the entirety of their pregnancies. It can be difficult to tell the difference between symptoms of pregnancy and those of menstruation. Especially if you already suspect that you may be pregnant. Because these reproductive features overlap in so many ways, many of the telltale signs are difficult to distinguish. Tender breasts, moodiness, cramping and back pain can all be signs of either pregnancy or PMS.

Another fact to consider is that it is extremely common to experience some spotting or vaginal bleeding in early pregnancy. It is less common in the first trimester, but 1 in 5 women experience some vaginal blood loss in their first trimester. Usually, spotting is the effect of implantation bleeding. Bleeding that occurs because a fertilized egg is attaching itself to the wall of your uterus. Like menstrual blood, blood from spotting is thicker and usually darker in color than regular blood. If you experience bright red, heavy flowing vaginal blood, you should consult a doctor immediately, especially if you think you may be pregnant. Heavy bleeding in early stages of pregnancy can indicate an ectopic pregnancy or a miscarriage.

Pregnancy Test During Your Period?

Now, you may be wondering if taking a pregnancy test during your period will skew the results of your test. After all, hormone levels spike during menses and there will inevitably be blood mixed with your urine. Well, let’s take a look.

In the most basic and easy to understand terms, the point of a period is to rid your body of an unfertilized egg. Every month, a woman’s body prepares itself for a pregnancy. Estrogen levels rise sharply, which causes the release of the egg. This is referred to as ovulation and the egg is ready to be fertilized by the male’s sperm. The body continues to produce excess progesterone and estrogen to prepare the uterus for a pregnancy. The uterus develops a thick lining rich in nutrient, which will sustain a life if a fertilized egg attempts to implant itself there. However, if the egg is not fertilized, the hormone levels drop back down to normal. The body needs to shed the lining of the uterus and so your period begins.

At home pregnancy tests work by detecting levels of human chorionic gonadotropin (HCG) levels in the urine. HCG levels are also present in blood and a pregnancy can be confirmed by at blood test at the doctor’s office. This pregnancy hormone is produced by the placenta and so is only present after the implantation of a fertilized egg on the uterine wall. HCG is measured in international units per milliliter and levels multiply quickly as a pregnancy progresses. An at home early pregnancy test can detect levels as low as 20 mIU/ml (the average pregnancy test will detect 25 mIU/ml and up) while a blood test from a doctor can identify levels as low as 5 mIU/ml.

A period or blood in your urine will not disrupt or skew levels of HCG in urine. The hormones that control menses are separate from the pregnancy hormone. HCG is only present where a successful implantation has occurred and you are indeed pregnant. So, in short, yes you can take a pregnancy test while you have vaginal bleeding and get accurate results.

If you suspect a pregnancy and are experiencing what you believe to be a period. It may be advisable to wait until the bleeding has stopped until you take an at home pregnancy test. This will allow you to assess whether your period is normal or if it is lighter than usual. Also, since the HCG level can multiply wildly in the early stages of pregnancy. A few extra days could mean the difference between a negative and positive result on a test. Waiting for the bleeding to stop will also allow you to determine whether your symptoms (cramping, breast tenderness, etc.) go away after the bleeding has stopped.

It is fairly rare for a home pregnancy test to produce a false positive. If you decide to take a test and produce a positive pregnancy test result. You should make an appointment with your doctor right away. This will be beneficial in confirming the pregnancy and your doctor can then determine if the source of the bleeding is a concern to you or the fetus.neemPositive pregnancy test with a red heart

To conclude, it is not unusual for women to experience some sort of vaginal blood loss in the early stages of pregnancy. This could be the result of a light menstruation, spotting or a vaginal bleed. If you think you may be pregnant and are experiencing heavy vaginal blood flow. You should consult your health care practitioner as soon as possible. A fluctuation in progesterone and estrogen is responsible for setting your period in motion. This process takes place to rid your body of an unfertilized egg and to shed the thick lining on the uterine wall.

At-home pregnancy tests detect levels of human chorionic gonadotropin in the urine. This hormone is produced by the placenta and as such will only present themselves in the case of a pregnancy. Vaginal blood loss or what you are interpreting as a period will not skew the results of a pregnancy test. You can take one while you are bleeding, it may, however, be advisable to wait until the bleeding has stopped.

In any case, if you take a pregnancy test and it is positive. You should make an appointment with your doctor or midwife as soon as possible to confirm your pregnancy with a blood test. Early detection of pregnancy will ensure your journey to motherhood is the joyful, exciting expedition that it is meant to be!


  1. I have been having light period for 4months now I did pregnancy test but came out negative but my breast is growing bigger what could be the cause

  2. with your roots and herbs you have enveloped my frown face with smile, slung to stand,tube tie burned alive, i used your herbs and root according to the instruction given it materialized,i have conceive now and delivered a baby boy,from letter A-z can’t speak how joyful i’m. contact him via on facebook (Oduduwa Ajakaye)

  3. I would like to point out some serious misinformation in this article… It is clinically impossible to menstrate during pregancy. The bleeding that occurs during implantation or pregnancy is

    A) Implantion bleeding:
    When the egg adheres to the uterine wall.
    B) Breakthrough bleeding:
    Which occurs around the time your period is expected and is believed to be related to the hormones that control your cycle ‘breaking though’ the ones that control your pregnancy. However, this only appears to be a (light) period and is not true menstration as your cervix closes for pregnancy. Shedding your uterine lining (menstration) during pregnancy would also remove the egg and would end any pregnancy.

    C) Miscarriage:
    Period like bleeding and / or worse bleeding and severe abdominal pains are potential signs of miscarriage.

    D) Ectopic pregnancy:
    Dark or watery bleeding during (typically early) pregnancy, also often accompanied by abdominal pains, is a potential sign of ectopic pregnancy – when the egg implants in the fallopian tube instead of the uterus.

    Please seek medical advice if you have any bleeding during pregnancy to ensure there is no serious problem. Bleeding during pregnancy is not necessarily dangerous but misinformation is and IT IS NOT POSSIBLE TO MENSTRATE DURING PREGNANCY!
