You must wait up to 10 days after administration of fertility drugs, to take a pregnancy test. Some false pregnancy test results could be a result of a hormone imbalance, including PCOS, a chemical or ectopic pregnancy, evaporation lines, and more. Make sure you’re following your test instructions correctly to avoid any user error. We made sure our early-result pregnancy tests are simple and easy to use with jargon-free instructions to get the clear answer you need. The pharmaceutical marketed under the name Pergonal is a mixture of lutenizing hormone, also called LH, and follicle stimulating hormone, or FSH, notes the Drugs website.
Like hCG-containing pharmaceuticals, it is used to stimulate ovulation in women and testosterone and sperm production in men. The similarity between these hormones leads to another interesting coincidence—ovulation prediction tests can be used as pregnancy tests in a pinch. Though they’re meant to check for LH, they’ll also respond to hCG because of the similarity between the hormones. Drugs can wreak havoc on a baby’s development in the womb, but even with how dangerous they are to the human body, they will not alter pregnancy test results. If you or someone you love is on drugs and has a positive pregnancy test, they are either pregnant or have a false positive for a reason unrelated to drugs. However, home pregnancy tests differ in the ability to diagnose pregnancy in women who have recently missed a period.
What can affect pregnancy test results?
It’s likely that the test is either faulty or expired, or that there wasn’t enough urine on the test to produce a result. Check the expiration date on the box and, if they’re not expired, take a new one. If this keeps happening, try using a different brand and take more than one to confirm your results are accurate.
This includes over-the-counter and prescription medicines such as birth control and antibiotics. Also, alcohol and illegal drugs do not affect pregnancy test results. If you have been trying to get pregnant you might be taking fertility medication to help speed up the process. Many women need the help of fertility medicine to help them be able to get pregnant.

False Negative Pregnancy Tests
However, if your levels are below 5 mIU, you are not pregnant and a positive result will not appear on your pregnancy test. Naturally, it takes the female body a week or more to begin producing hCG after an egg is fertilized. From that point, it takes even longer for the hCG levels in a woman’s urine to rise. In fact, it takes anywhere from two to three days for levels to double. Since they start so low, it can take a few weeks before they are high enough to be detected by a home pregnancy test.
On most pregnancy tests, a positive result is indicated with two lines and a negative result indicated by one line. An evaporation line looks like a faint, colorless line that appears to be a positive result. To avoid this, read your test instructions and wait to look at your results no earlier or later than they say to.
Can Medication Affect Pregnancy Test Results?
You usually conceive and become pregnant after the implantation takes place. Unfortunately, sometimes the pregnancy fails to go any further and a miscarriage happens. If you take a pregnancy test during this period, you may still have high HCG in your system, leading to a false positive result. You usually experience this problem due to genetically abnormal pregnancies.
The risks might not include an inaccurate pregnancy test result, but they are far worse. Certain drugs such as clomiphene citrate interfere with ovulation test results – generally in the form of a false positive. It generally causes a false positive only in case an ovulation test is taken too early of the menstrual cycle. Hence, drug manufacturers generally suggest to not to take test with the ovulation predictor kit until several days after the last dose of clomid.
There are certain medications that may lead to false pregnancy test results, such as fertility treatments. A lot of fertility treatments work by providing synthetic hCG to help with ovulation, which could be mistaken by a pregnancy test as the real hormone. Pregnancy Tests Fact Sheet, most over-the-counter and prescription medication will not affect the results of a home pregnancy test, including antibiotics and birth control pills. The only medicines that can display a false positive test result are those that contain the pregnancy hormone hCG, such as most medications used to treat infertility. These days, many over-the-counter pregnancy testing kits are available in the market. These kits are generally 97% accurate and cheap and hence are preferred by many women to detect pregnancies.
The best way to ensure that your test results are accurate is to visit the doctor. They’ll confirm your pregnancy and monitor it through an ultrasound to ensure everything is developing correctly. Ectopic pregnancy is a severe medical emergency that requires immediate medical care.
So if you are on fertility medicine, go to your doctor for a pregnancy test. Some women do not pay attention to the expiration date mentioned on pregnancy tests. Therefore, you need to ensure that you are not using faulty or expired pregnancy kits to get accurate results.
These can include anything from premature labor to low birth weight to learning disabilities and many other birth defects. If you weren’t trying and it happened regardless, don’t let a few glasses of wine cause you to panic thinking that you’ve harmed your baby. In fact, call your doctor and discuss this with him or her to help you ease your fears and continue with an otherwise healthy pregnancy.
Additionally, taking a test too soon after a recent miscarriage or chemical pregnancy can detect hCG levels that have remained in your body. This test will show a positive result, but only because the pregnancy hormone is still in your body. Similarly, an ectopic pregnancy will most likely give you a positive test result. Ectopic pregnancies still produce the hCG hormone even though they are developed outside of the uterus.
A false positive test is one that shows you are pregnant even though you are not. It’s important to follow directions exactly when taking pregnancy tests, otherwise you could end up with a false positive or false negative result. If you’re following the instructions correctly and you’re still concerned that your results are incorrect, you should consult your doctor. However, fertility drugs / medications containing hCG may interfere with home pregnancy test results. All tests are different, but false positives can be caused by problems with the test or issues interpreting your results.
