Can drinking too much water dilute your pregnancy test?

Hi- As of today my period is going on 5 days late. I took a pregnancy test this morning, but it was negative. I thought I read somewhere that drinking a lot of fluids can dilute your urine and affect the results of a pregnancy test. I drink about 5-6 glasses of water a day while I'm at work, then I drink 2-3 glasses of decaf tea when I get home at night. I'm just wondering if what I read could be true? I've never been this late on my period, my normal cycle is 27 days, and I've rarely had times where it was 29 or 30 days, but today is day 31. (I'm counting the day I missed my period, the 27th day, as the first day of being late). I'm going to take another test tomorrow or the next day if I still don't get my period. I was just sure though the test would be accurate if I'm 5 days late. I know stress can affect your period but I'm not stressed at all about anything, and stress has never affected my cycle in the past. Anyway, has anyone heard of this? Thanks for your help!

Did you drink this morning before testing? Did you use the first wee of the day?

Drinking too much water can dilute your urine, but usually your morning urine is the best to test with.  The test may be accurate, but some women don't get positive results as soon as others.  A blood test would be the most accurate, so I would contact your doctor if period doesn't come.

Yes drinking to much can dilute your urine thats why they say to use FIRST MORNING URINE. Or hold your urine at LEAST 4 hours.  I know when I was pregnant I was unable to hold it for 4 hours. I held it for almost 3 and got my +.  

If you don't get a + tomorrow when you test again you might want to go to your Dr. for a blood test. Your hormone level might not be high enough to read on a HPT.

Yes, if your urine is too dilute it will be harder to pick up HCG.  However, using first morning urine, which tends to be more concentrated, should give you a reasonably accurate result since the majority of fluids you drink throughout the day/evening have been passed and the urine will re-concentrate overnight.

There are a number of reasons why your period could be late.  I would suggest you wait until the weekend and retest w/ FMU using a sensitive HPT if you dont have your period by then.

i' had a coworker who also had a regular like clockwork 28 day cycle. she's 34 and when she missed her period she KNEW she was pregnant but didn't get a positive until a week later!

Wishing you luck!

Yes, I did use first morning urine. Well, I'm thinking if I don't start today I'll take another test in the morning, and maybe still get a blood test if it still says negative. Thanks for all your help! I'm just confused because every now and then my period will be a couple days later than usual, so it may just be a weird thing this month, but then again maybe not! Well, I will keep everyone posted if I find out I am! :)

well...i took another test this morning, still negative, but still no period. im 6 days late now! im off work tomorrow (closing on our first house and moving!) so im going to go to the doctor early early to get a blood test done. i dont have any symptoms though... wish me luck!

[tarajanes]

Its very possible you ovulated later than you normally do,there is no set date each month a women ovulates.anything could have delayed it,hence why the late period.but then again maybe you are preggers,wishing you the best of luck !!!!!

good luck and hopefully you will get your BFP!!

well.....no baby yet for me. i finally got AF on Friday, 8 days late. i have no idea why my cycle was 34 days just out of the blue. my husband and i were ttc for awhile, gave up after 5 months and decided it will happen when its supposed to. everyone says to just stop trying and it will happen. im very disappointed because i thought it finally "just happened" and i really got my hopes up. thanks a lot AF! i hate to be ms negative, but everyone i know is getting pregnant "accidentally" and im having a hard time. i really am happy for them but it really makes me upset. sigh..... im new to this forum, and thanks to the ladies that responded to my first post for your support :)

i'm sorry you got AF but don't give up! You(and I)are still young and your body is in perfect shape for giving you that baby!!! It will happen....i promise!
