Umm, that depends. Did you read the first two within the correct window of time? Pregnancy tests are invalid after 10 minutes. If you read the results after that, you might have seen an evaporation line.

If you ARE pregnant, it's also possible that your urine was too diluted to trigger positives on the last two tests.

Buy another test and take it first thing tomorrow morning with your pee that you've been holding all night long (first morning urine). That should be accurate. Or, if you're still concerned, contact your doctor and ask for him/her to test you.

positive

your most likely 99.9% pregnant

unless you let the positivetests sit for a long time and the 2nd line was just an evap line

but if it showed up right away then your pregnant!

got to the doctor thats about all i can say cause i took one and it didn't take so i went to my health department. and i took one there then went to the doctor and every time i go but thats just a percaution..
