Icky, but effective! The more diluted your urine is, the less hCG will be present — and the less likely you are to get a positive result. What dilutes your urine? Who knew? Just like any other mass-manufactured product, pregnancy tests can arrive at the store damaged, expire on the shelves or in the back of your bathroom cabinet, get exposed to too-high or too-low temperatures during transit, or just… not work.
If you have a legit reason to think something may have been wrong looking at you, tests from the Dollar Store checkout line , by all means buy a fresh test from a different store and try again. Because we like to keep you in-the-know, there are some less-common scenarios that can lead to a false negative on a pregnancy test:. You know what medical condition feels a lot like pregnancy? The same body system and hormones are involved, so it makes sense. If you can, try to avoid the symptom spotting trap.
Therapies that increase progesterone or block estrogen can cause symptoms that mimic both PMS and pregnancy, including nausea, bloating, tender breasts, and changes in mood. Almost everything having to do with pregnancy involves waiting: waiting until your period is due to take a pregnancy test, waiting those looooooong 3 minutes to check the results, waiting until the next month to try again, waiting 9 whole months for your baby to be born once you actually get pregnant.
But even if you are actually pregnant, that drugstore test might not give you the right result. Everything from medications to medical conditions to the time of day you take the test can mess with that positive and negative sign.

A false-negative pregnancy test may happen if you don't take the test first thing in the morning. Depending on the cause of your lack of menstruation, you could ovulate again at any time. Consequently, you could get pregnant and not realize it since you won't miss a period.
If your period is one to two weeks late, and you still are getting negative pregnancy tests, a visit to your gynecologist for a pregnancy blood test is recommended. Depending on your circumstances, many providers will want to induce a "period" if you go more than two or three months without menstruating. If your cycle used to be regular but has become irregular, or your periods are irregular for more than three months after stopping birth control, you should see your provider.
Irregular cycles can be a risk factor for infertility. A missed period combined with a negative pregnancy result can be confusing but there are a number of explanations. Most often, if you aren't pregnant, your period is just a bit late. If you are pregnant, it's likely you didn't wait long enough before taking the test. Regardless of the cause, don't ignore worrisome symptoms. Get diet and wellness tips to help your kids stay healthy and happy.
