Disappearing positive?

[mamabambi]

So, I took a pregnancy test 12dpo just on the off chance as I was due on and wasn't (never happens) and got a BFP for about a minute, and then it faded away. Took another test and got a BFN but the test didn't work as fast as it normally should and I had to actually pee on it again to get a result.. Do you think either test is faulty? I'm so confused, could I be pregnant?I hate not knowing! I got a ton of false negatives for a month until I found out I was expecting my first!

Can't be much help I'm afraid, but didn't want to read and run! I'd take another couple, preferably a different brand - that seems a bit weird... Mebbies give it a coupla days too?

And try in the morning rather than tonight, give yourself the most accurate result.

I had this with a first response and tescos own seemed to be the best! Good luck x

I've found Asda's own brand is good for early results... could try that too :-)
