I just had a baby a little over 8 weeks ago.  My husband and I had a few oops and I was worried about being pregnant so I decided to test.  I do not know for sure if I ovulated but I have not had my post postpartum menstrual cycle.  I tested on Monday it came back negative, tested again on Tuesday and got a faint .  I called my dr office and was instructed to go in for a blood test.  It came back negative, the test given was a \"Yes/No\" blood test not a beta.  It came back negative.  Could the test be incorrectly negative?  Or possibly a false positive?  Does a diuretic affect pregnancy test results?  I took a diuretic the day before would that affect my results on the home pregnancy test or the blood test?
Hi there, please don't panic. Usually, diuretics lead to increase urine Formation. And dilution of the urine.  This might lead to false negative results. If you have history of regular cycles and also there is history of unprotected sex act on and around the days of ovulation, then you need to rule out pregnancy. If urine pregnancy test is not predictive, then please get blood beta Chat Doctor test done.  Results above 25 confirms the pregnancy and results below 5 rule out the pregnancy. I will suggest you to get proper sex counselling done.  This will help to prevent unwanted pregnancy and STDs. I hope this answer helps you. Thanks.
