I took a pregnancy test yesterday. It was negative. Something told me to look at it again this morning and it had a very tainted yellow line next to the very bright pink line. I read in an article that a test is only correct up to 10 min otherwise it evaporates and the results may change. Let me know what you guys think? Also, should I take another one just to make sure?

Thanks.

The tests are only good during the 10 minute time line. If you took the test yesterday and read it today, what you saw was called an evaporation line. It does not mean you are pregnant.

If it would make you feel better, take another test in the morning using first morning urine and read it during the 10 minutes, no longer than that. After the 10 minutes just throw it away.

Thank you... I guess I just needed someone else's opinion then the article's! :)

You are very welcome. I will tell you though, that this is not my opinion. As a nurse extern in labor and delivery we get these questions quite often. Good luck to you dear.
