if you drank alot of water it could give you false results because your urine is diluted.
i drank 3 cups around 500 ml but before sleeping and then after like 5 hours in the morning i had the test and it was negative
I don't know if water can affect result specially before 5 hours
In addition i am anxious about the medicine Tegretol can it affect the result ??
Thank you for helping
I've read and heard Tegretol can affect a test. You need to see a doctor for a blood test to determine if pregnancy is true or not. You did have sex at a good time to get pregnant, so you would need to be seen.
I checked it out and it says it may intefere with the test results. I would call my doctor and see about getting a blood test which is the only accurate way at this point. Good Luck.
