You’ll get the IUI a day or so before your expected ovulation window. If you get a false negative pregnancy test result, it's likely either because you've taken the test too early or you haven't taken it correctly as outlined on the label. Most medications won't affect the accuracy of home pregnancy tests, although fertility drugs containing the hormone hCG are a notable exception.
But some providers will see you sooner, especially if you have a medical condition or have had problems with a pregnancy in the past. It's especially important to see your provider sooner if you're having nausea and vomiting, vaginal bleeding, or abdominal pain. Some women take more than one home pregnancy test just to be sure – but that's not really necessary.

You continue to get negative test results, but your period doesn't start. Your provider may suggest you take a blood test to check for pregnancy, which may be more accurate than a home test. Also, some health problems may lead to missed periods. If you're not pregnant, your health care provider can help you find out what's causing missed periods. The timing of ovulation makes a difference in the accuracy of a home pregnancy test. A fertilized egg also can implant in the uterus at different times.
More-sensitive tests need less HCG in urine to show a positive result. If you're not sure which type of test to use, ask a pharmacist. For the most accurate results, always test with your first-morning urine and follow the instructions carefully. That’s why it’s important to speak with your doctor if you’re in fertility treatment. They can explain how these meds may skew your pregnancy test results. So if you get a positive test, followed by a negative result a few days later, you may have had an early miscarriage.
How Soon Will a Blood Test Detect Pregnancy?
All home pregnancy tests measure the amount of a specific hormone known as human chorionic gonadotropin in your urine. However, women with a history of ectopic pregnancy or current abdominal pain should call the doctor right away to be examined. Ectopic pregnancies implant outside of the uterus and produce hCG, resulting in positive pregnancy tests. However, these pregnancies can cause abdominal bleeding and prompt medical care is necessary.
You've had a miscarriage or terminated a pregnancy in the past eight weeks, or have a molar pregnancy. Eating a diet rich in fruits and vegetables will help you get the key vitamins and minerals needed to support the growth of the fetus as the pregnancy progresses .

The Importance of Progesterone Production During Early Pregnancy
These things usually happen if you take the test too soon, before your hCG levels are high enough. If you get a faint line on a pregnancy test, wait a few days and test again. But you can still get what are called false negatives or false positives. You can take another pregnancy test a few days later .
Baseline hCG levels, early pregnancy hCG levels, and hCG doubling time vary from woman to woman and from pregnancy to pregnancy. Along with the date of implantation, these factors will influence how early you can get a positive pregnancy test. If you don’t know when you ovulated, you can approximate this window by taking a pregnancy test two days before your period is due. According to normal reproductive physiology the pregnancy test will be positive around 8 days after unprotected sex if you are pregnant.

If your period doesn't begin, take the test again in a few days or in one week. It's especially important to do this if you took the test before or right after a missed period. But it is possible to get a positive result from a home pregnancy test when you're not pregnant.

After a fertilized egg implants into the uterine wall, a woman’s body starts producing a pregnancy hormone called human chorionic gonadotropin .
There are, however, some brands of pregnancy tests that claim they’re sensitive enough to detect hCG up to five or six days before your missed period. Still, you’ll get the most accurate results if you can wait until the day your period is expected. Blood tests aren't often done to detect pregnancy because they are expensive and at-home urine tests are quite accurate and sensitive. However, people who are undergoing fertility treatments may have blood tests as part of their care. This pregnancy test has clearance from the FDA to say it can detect pregnancy hormones 6 days before your missed period. There are plenty of other early pregnancy tests on the market.
