Hi Shan23, Welcome to BB!

From what you have said, if you are UTD you would already be about 5 weeks along?? If you are willing to hold out it can't hurt to wait a couple more days then use the FR with FMU... but I wouldn't be able to wait and I would use it tomorrow morning!! FR is one of the most sensitive tests on the Australian market and will hopefully give you an accurate result.

If you read the tests within the correct time frame it is unlikely that you would get two false positive results. An evap line takes a while to appear. Can you photograph the tests and post them here on BB??

If you want a definitive answer, I would head to the doctor and request a blood test. This will test the level of HCg (pg hormone) in your blood and tell you for sure if you are UTD!

Good luck, let us know how you go!!
