why would a positive home pregnancy test fade away?

Question

I took 3 home pregnancy tests. they all came back as a very faint positive within a minute. but a couple weeks later the positive line has disappeared. why would it do that? It never happened when i had my first child

Answer 1

It's a chemical reaction to the pregnancy hormone. Store in a cool, dry and dark place. Light will cause colors to fade. Heat and moisture help things react chemically. Different brands are probably designed a little differently. I've seen one that has not faded in four years and counting.

Answer 2

in case you're nevertheless 4 days far flung from having your era, and you observed even the faintest of lines, then there's a sturdy danger you're pregnant. After 10 minutes the assessments exchange into untrustworthy, so it is common for it to vanish after 8 minutes, and for it to be so mild. Your being pregnant hormones are could be very low. examine lower back in some extra days and notice if the line will become any darker.

Answer 3

In the instructions of the ne I took, it says that the line will disappear in like 45 days. It doesn't stay there forever.

Answer 4

You're supposed to disregard any results after the initial results.

Sometimes it just happens that way (it's liquid being absorbed that gets the results, maybe further absorbtion caused it to spread to much or it evaporated along with the results....who knows).

Answer 5

It was probably the brand of pregnancy test. Dont worry, your still pregnant...lol but yeah mine did the same thing.
