Can I take a pregnancy test after drinking a lot of water?
Drinking water—or any fluids—can, in fact, affect the results of an at-home urine pregnancy test, especially when taken very early in the pregnancy. When your urine becomes diluted by drinking lots of fluids, it takes on a pale yellow or clear color, and the urine concentration of hCG becomes lower.
Do all pregnancy tests turn positive after a while?

Too much hCG in the urine If you have too little, (if you took the test too early or diluted your urine), it won’t be detected. If you have too much, (if you took the test too late), the test strip may not be able to bond to any of the molecules, possibly showing a negative result.
Is it possible to not have enough hCG in your urine?
An early pregnancy test might pick up very low amounts of hCG. However, it’s possible that you don’t have enough circulating hCG to get a positive result even on a sensitive test. Another common reason for getting a false negative is not having enough hCG in the urine you test.[ad_2]
