I have had two children and both times my tests didn't show I was pregnant until I was atleast 3 weeks pregnant
You usually aren't supposed to take a pregnancy test until your first missed period to get the best results.
Pregnancy tests, especially early-stage home tests, are never 100% reliable.
Yes it can if you have tested too early. Here is a link for information on how pregnancy tests work: http://thefertilityshop.com/fertility/pregnancy-tests-work-a-17.html
no, especially if there was no penetration
If your stomach is growing and you have negative pregnancy tests, you need to see a physician. This could be a result of a benign mass (cyst), an infection, or any other number of things that could be harmful in the long run if ignored. You shouldn't feel movement in your abdomen early during the pregnancy.
Go to the doctor to get a real test.
Urine pregnancy tests normally detect >25. A result below that could indicate very early pregnancy, or the tail end of a miscarriage.
No, UTIs do not affect the accuracy of pregnancy tests.
Norethindrone, a progestin used in various contraceptive methods, is not typically known to cause false negative pregnancy tests. Pregnancy tests detect the hormone human chorionic gonadotropin (hCG), which norethindrone does not affect. However, if the test is taken too early or not according to the instructions, it may result in a false negative. If there are concerns about pregnancy while taking norethindrone, it's advisable to consult a healthcare provider.
Yes as they are negative you can conclude, the test is negative and nothing to worry.
All home pregnancy tests*
if you have been confirmed as pregnant by the doctor - it is still possible in these early stages of pregnancy for tests to come back negative, i would check with the doctor to be sure.
Yes. Home pregnancy tests only read up to a certain amount of hCG or the pregnancy hormone. Anything above that number would read negative.
