Did you do all three tests with your first wee of the day? All the same brand test?
@Amy yes first wee of the day and yes all same brand tests
It might be a chemical pregnancy have you heard about that? I had an ectopic and the pregnancy test was getting darker. If tits gone back to negetive sounds something like a chemical could have been the cause Usually they will get darker… did you make sure you read the results within 5 mins of the positive one?
I would go and buy a first response or a clear blue digital as a comparison
I had a positive then negative then positive….maybe give it a few days?
I'd go to your early pregnancy centre or GP they may need to do test to check you if you've had an ectopic pregnancy
