Are Pregnancy Tests Ever Wrong?

pregnancy test

You purchased the most expensive test at the drug store. It included two tests inside the box, just so you could be doubly sure that the answers are correct. And now you are ready to take it. That is one of the most exhilarating and frightening moments any woman will ever live through.

Pregnancy tests have immensely improved over the years. They work by measuring the amount of HCG, which is a pregnancy luteinizing hormone, in your urine.

Waiting for the test can seem like hours; although it only takes seconds to see the colors run through the windows. Then, you get your answer. The next thing is to wonder, could it be wrong? After all, you feel different and somehow pregnant, but the test says negative. Or – how can you really be pregnant when you feel nothing at all?

Pregnancy tests have immensely improved over the years. They work by measuring the amount of HCG, which is a pregnancy luteinizing hormone, in your urine. You should use your first morning urine because it will have the strongest concentration of HCG, which means even if you are only days pregnant – it should register.

Today, most over-the-counter tests used to confirm pregnancy, measure around 5mcg of HCG, which is extremely scarce. Other, cheaper versions will measure 10mcg of HCG. Basically, your body starts producing HCG the minute you conceive, and will double the amount of HCG daily. So if today your levels were at 20, tomorrow they will be at 40, and the day after that they will be at 80. This is why pregnancy tests normally tell you to wait a day or two before retesting. With each passing day, your levels increase dramatically.

Your body starts producing HCG the minute you conceive, and will double the amount of HCG daily.

One of the problems with them is that many women test so early nowadays, up to 7 days before a missed period, that there often isn’t enough HCG in your system for it to be completely accurate. Additionally, your body may not have properly implanted yet – a critical step in pregnancy, giving you a false positive if implantation is unsuccessful. And had you not taken a test, your menstrual cycle would have started normally and you would have never been the wiser to the pregnancy. By the same token, you may take a test too early when your pregnancy hormones are just too low to detect through a urine test.

    Today I was supposed to start my period but it never came so I went n took a dollar store pregnancy test and the line that came out was perfectly in the middle of the C and the T. Could there have been something wrong with it?

    ok so I had two positive tests with one brand of home tests and a negative on another brand within two days. I am waiting for blood test results but was wondering what you ladies think. Am I likely to be pregnant?

    Could I still be pregnant and went to the free pregnancy center and they Said it was negative one line but my stomach is starting to grow

      It is possible that you’re still pregnant. First maybe wait couple days, and then take another at home pregnancy test. Sometimes people just test too early and there’s not enough HCG built up in your system. Also, be sure to test using your first pee in the morning. If it still comes out negative in a few days, yet you think it could be wrong, it may be time to go see a doctor and have a blood test done to confirm. Good luck with everything!!

    I think the tests are accurate when they give you a result of positive but on the negative side i see them being wrong

    I took 2 pregnancy test one morning and one barely showed anything the other was negative. So I tried a different brand 2 days later and it came back positive with bold lines. Just to be sure I tried another teat that happened to be the same as the first 2 I took and once again a negative. But I am now 7 months so it was clearly wrong.

    i took 2 pregnancy test on july 2 the first didn’t show anything. blood test came back positive on the 3rd though.

  12. For my first pregnancy I took 3 tests and for my second pregnancy I also took 3 tests. They were all positive I just think that I was surprised.

    I tested this morning n got a dark pink n a faint pink even if I got a faint pink could it still be negative????

  14. Avatar of Alexandria Alexandria says:

    With both my pregnancies they came back negative, and I bought the most expensive ones and the dollar store ones. I had to go to the doctors and have them test me. I have wasted way too much money on them. from now on its straight to the doctors for me.

    • Avatar of Alison Alison says:

      I’m having morning sickness, heartburn, and my breasts are super tender (and getting big). We’ve only been trying for about two months now, and all of my home tests have come back negative. My SO and I are both certain I’m pregnant. It’s good to know that there are false negatives. Now I have even more reason to just go to the doctor for testing. Thanks!

    If your not sure if its right and don’t want to spend a lot of money the dollar store ones work.

    Took a test today, but negative. Wish it was wrong but dont think so.

  22. Avatar of Hope Hope says:

    Go to the doctor. If you don’t have a period and your home pregnancy tests say negative, then there’s a chance either something’s wrong or you are in fact pregnant.

  23. Avatar of Julie Julie says:

    I have heard that the lightness and darkness of the line has no meaning. Although, when I took my test I was 2 weeks late and the line was really really dark.

  24. what if you’ve missed 2 months of your period and the pregnancy test are still reading negative?? i haven’t been on birth control sense Sept. of 2011 and i have all the signs and symptoms of pregnancy but the test keep saying no!

    • Avatar of Lynette Lynette says:

      With my first, I was 6 weeks pregnant and even the blood test said I wasn’t. However, I knew I was and two weeks later the tests finally proved it (and showed on ultrasound). I have PCOS and other hormone issues, so this could have affected it, but if you really think you are, I would make the dr appointment to be sure.

      • Avatar of Heather Heather says:

        I went through 2 tests at home and went to my Dr who gave me another test that was negative. She sent me to an Ob/gyn who told me I was just cranking out some good eggs and to wait a couple more months. After waiting until my next missed period did I finally get a positive. Then we went for our first checkup and found that I was already 8 1/2 weeks along.
