Is Crystal clear known to give false positives?

Question

I tested with crystal clear last friday and it was a faint positve the line was extremely thin.

Now today (friday) tested with the same brand and got a negative?

Answer 1

I dont know about that brand never even heard of it, but its fairly uncommon to get a false positive

Answer 2

No, false positives are extremely rare- it is detecting hormones in your urine that are signs of pregnancy. Call your dr and set up an appointment for a blood test. .  

Answer 3

use a different test and if u r still not sure...go to ur doc, better safe than sry

Answer 4

There are no false positives. If there is a positive its because there was HCG present in your blood stream. Did you test with your first morning urine this morning? Was your urine too diluted? You should get a blood test. Or try First Response.
