Pregnancy test and Medication

[nanom]

Hello
I had a home test on day 31 early morning, but before sleeping i have drunk 3 cups of water and the result was negative
my period is 27 , 32 or 35 days the last 3 months were 27 days

I am taking tegretol medicine daily 500 mg daily

last intercourse was on day 9 after my previous period i am anxious as we were not planning for pregnancy now and i have read that tegretol may affect the result and give false negative
any help please

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.

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 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

if you drank alot of water it could give you false results because your urine is diluted.
