The pregnancy tests you get at the drugstore work 99 out of 100 times. They're just as accurate as a urine pregnancy test that you'd get at a doctor's office. Pregnancy tests work by checking your urine (pee) for a hormone called human chorionic gonadotropin (HCG). Your body only makes this hormone if you're pregnant.

So when is hCG detectable during pregnancy? Urine pregnancy tests can detect hCG levels when they reach 20 to 50 milli-international units/mL, while blood tests are positive at 5 milli-international units/mL, Lamppa says.

They generally double every 24 hours during the first 8 weeks, peak around 10 weeks, and then decrease. 2 Considering that pregnancy tests detect hCG in your urine, it's normal for the test line to get darker as your first trimester progresses.

Can Too Much Pee on a Pregnancy Test Make It Negative? Urinating too much on a urine pregnancy test should not cause a false negative result. But diluted urine, or urine with a higher water content, can impact a pregnancy test by skewing results.

The hook effect incorrectly gives you a negative result on a pregnancy test. This can happen during early pregnancy or in rare cases — even into the third trimester, when it's pretty clear you're preggers. During pregnancy your body makes a hormone called human chorionic gonadotrophin (hCG).

hCG is a hormone produced by your placenta when you are pregnant. It appears shortly after the embryo attaches to the wall of the uterus. If you are pregnant, this hormone increases very rapidly. If you have a 28 day menstrual cycle, you can detect hCG in your urine 12-15 days after ovulation.

HCG is normally only present in your body if you are pregnant. Any positive line, no matter how faint, means your result is pregnant. Levels of hCG in your body will increase over the course of your pregnancy. If you test early, your hCG levels may be still be low and you'll see a faint positive line.

Symptoms of early pregnancy include missed periods, nausea and vomiting, breast changes, tiredness and frequent urination. Many of these symptoms can also be caused by other factors such as stress or illness.

“The false negative rate, if done appropriately, is less than 1%.” If someone waits until the appropriate point in their menstrual cycle and ensures that their urine is concentrated enough at the time of testing, then it's highly unlikely that an at-home pregnancy test will provide incorrect results, he explains.

In most women, symptoms may begin to appear as early as one to two weeks after conception. First symptoms of pregnancy timeline: Pregnancy officially begins two weeks after your last menstrual period. Implantation may occur at 1 to 2 weeks and cause light spotting, discharge, and cramping.

The only guaranteed way to check for pregnancy is with a pregnancy test. However, people can check their cervix at home. To do this, they should clean their hands thoroughly before placing a finger into the vagin*. The location of the cervix is in the top wall, nearest the stomach, and it should feel like a small bump.

Your doctor can give you a blood pregnancy test as early as 11 to 14 days after ovulation. To perform a blood pregnancy test, the doctor draws blood from a vein in your arm. This blood is sent to a laboratory for testing. The results of most blood pregnancy tests take at least a couple of days.

These show results much faster than a pregnancy blood test, usually within a few minutes. Both types of pregnancy tests at a doctor's office are 99% accurate.
