Hello,
I'm just wanting to know who has had a false negative when testing with dilute urine and was this after your period was late?
I am nearly 39 weeks pregnant, so I'm just asking this out of interest (and I'm a bit bored on mat leave so over thinking pregnancy things). When I got my due date from the 12 week ultrasound, it nearly a week earlier than I expected from LMP. I did take a couple of pregnancy tests way back in June/July when I first found out. The first one I took was when my period was late and it was negative. If my ultrasound date is right, I would have been 4+6 when I took that test (or 20 dpo I think). I did do it on an evening with quite dilute urine. Appreciate fmu is better, but if ultrasound is right, I have always thought I would have got a bfp on the first test. Whilst I know ultrasounds are generally considered more reliable, I'm wondering if my ultrasound due date is a little early. It was a cheap test, one that says it's accurate from day of missed period and "up to 4 days before".
So, has anyone had negative tests several days after a late period due to dilute urine? Or alternatively, have you had positives with dilute urine at this stage?
Thanks
