False-Negative Pregnancy Tests

At Your Options Medical, we have found that when many of our patients have a negative pregnancy test result, they assume they are not pregnant. However, this is not always the case. False negative pregnancy tests do occur. Here is how it works:

A urine pregnancy test detects the hormone called hCG (Human Chorionic Gonadotropin). This is the hormone your body produces during pregnancy. When urine is being tested for the presence of this hCG hormone and a woman is pregnant, the result of the pregnancy test should read positive. However, there are a few reasons a pregnancy test can give a false test result including the following:

  • In early pregnancy, the hCG hormone levels may be too low for a pregnancy test to detect. The earliest time to test for an accurate result is 7-10 days after a missed period.
  • The best time of day to take a pregnancy test is first thing in the morning when a woman’s urine is highly concentrated. Because urine may be less concentrated later in the day, the test may not be able to detect the hCG hormone.
  • If you have had a negative pregnancy test, but are experiencing pregnancy-like symptoms such as nausea, vomiting, tiredness, loss of appetite, etc. it is always best to contact your doctor to access for causes unrelated to pregnancy.
  • There is always the possibility of human error when performing home pregnancy tests. It is important to follow the manufacturer’s instructions. Most pregnancy tests require you to let the test set for 3-5 minutes. If the test is left beyond the recommended set time, this could produce a false test result.
  • If you had a tubal ligation (i.e. tubes tied), are experiencing pregnancy-like symptoms, and test negative on a pregnancy test, contact your medical doctor to assess for causes unrelated to pregnancy.

If you think you might be pregnant because you have missed your period, know that there are other reasons besides pregnancy. To learn more, check out our blog.

  1. I have had my tubes tied for a year now my period have been irregular since I stop breastfeeding 6months ago. Now I’m experiencing pregnancy symptoms with tenderness in my breast like pins and needles and nausea but not throwing up every time I drink coffee or without drinking coffee.I have taken 2 pregnancies tests and both are negative but I’m still experiencing pregnancy symptoms. Do you think that I’m pregnant?

    1. Hello Keiyania,
      Thank you for reaching out to Your Options Medical.
      I understand it can be difficult to track your periods when you are irregular. I cannot say whether you are pregnant or not. I would suggest that you see your doctor and request a blood pregnancy test if you are still experiencing pregnancy symptoms and have not started your period. This would be a more definitive test to determine if you are pregnant or not.

  2. Please is it possible to have a false negative test one month of having unprotected sex? I had sex on 21, 22, 23, 24 and 25 june. Few days to my period, that is 4 and 5 july, I had few drops of brown spotting in my pant. I had a test and it was negative. My period is delayed over a week. My palm and feet are always warm, I most often experience headaches, i have severe lower back pain, my breast are a bit heavy without pains. I checked on Monday and it was negative. Am confused. Should I give my self some weeks and test again? Can I be pregnant and still test negative?

    1. Hi Lynet,

      Thank you for reaching out to Your Options Medical.

      Yes, it is possible to have a false negative test at this point.
      Typically, we recommend the best time to take a pregnancy test is one week after you are due to start your period. Also, the best time to test is first thing in the morning. If the test reads negative, we recommend testing again in about one week.
      You may want to consider requesting a blood pregnancy test from your primary care physician or OB/GYN as these tests are more accurate at detecting pregnancy than urine tests. This way if pregnancy is ruled out, your doctor can further assess your symptoms. If symptoms persist and pregnancy tests continue to be negative, seek medical attention.

  3. My tubes are tied and my period are 10 days late when should i take a test? And what if it’s negative

    1. Hello Sharnice,
      Thank you for reaching out to Your Options Medical with your question.
      There a a number of factors and issues that can affect your period cycle. Medications, diet, exercise, and illness are some of those factors. the best time to take a pregnancy test is at least a week after your missed period, first urine in the morning. This will have the highest concentration of the day of HCG in your urine. If you test negative, and still don’t start your period, you could request a blood pregnancy test from your doctor to be sure.

      I am wondering if you have been tested by the facility you got your embryo transfer from. They would be your best source of information and care during this time.

  4. Hello-
    My period came 6 days late and was very heavy day one. I did have rigorous sec the night before and was a bit sore. Day 2 I had very light bleeding. Three and 4 I didn’t use any tampons as it was barely light. I took a test Wed night and Thursday morning, but both came back negative. I have cramps still especially on the right side of my lower belly. It feels like a cyst which I have had big ones before. I also have a hydrosalpinx on that side same side. I also had no usual PMS symptoms (no breast tenderness, etc.) this time. I am not sure if this is just a weird irregular period or if I should be concerned. Thank you for your help.

    1. Hello Haley,
      Thank you for reaching out to Your Options Medical with your question.
      There are various factors that can affect your period, such as medications, stress, diet, exercise and illness. At this point, not having a period for 3 months and having negative pregnancy test results, I would suggest you follow up with your doctor to help determine the cause of your missing periods.

  6. Normally my cycle last 4 days. However, there last two months my cycle has come twice in both months and last only 2.5 days. I’ve taken 4 pregnancy test and they’ve come back negative. I even waited to do so first thing in the morning. Could I be pregnant?

    1. Hello Shon, Thank you for reaching out to Your Options Medical with you question.
      Period cycles can change from time to time and can also be affected by a number of factors such as medications, stress, age, diet, exercise and illness. It is not possible to tell why your periods have not been as you normally have. At this point I would suggest you contact your doctor for a blood pregnancy test and follow up with him/her if it is negative to determine the cause of the change in your cycle.

  7. my last periods was June 1. I’ve never been more than a day late in my life and I track my periods using an app. In the first month, I had tender boobs (I haven’t had sore boobs since I was a teen )and wacked out emotions. I also couldn’t stop eating.. I didn’t have my period in June when I should have, but I got one day by where I thought my period had come…but the flow was very short, light and unusual colored dark brown. Come July 7, I went in for a blood test.. it was negative. I thought…ok..I skipped. let’s face forward.., It’s July 25 and I’ve skipped my second period., Which was due 7/21. I’m naucous.. like major naucous…I go in on 7/23 for another blood test..it’s.negative.

    Could I still be pregnant? And if I’m not, what the hell IS wrong with me?

    1. Hello Julia,
      Thank you for reaching out to Your Options Medical with your question.
      It sounds like you have done appropriate things such as getting blood pregnancy tests. I am wondering.. do you have a doctor that you are following up with?? At this point you may want to consider a medical follow up to determine the cause of your symptoms. Periods can be affected by many factors, but because you are also having other symptoms with your missed periods, I think a medical follow up is your best option at this time.
