2 Positive tests followed by 4 negative

[AlexG1991]

Hi everyone
Period didn't come on sept 29th as expected according to my flow app. Took a test October 3rd, and was negative, but looking back a hour later there was a strong line. Took another test October 4th and was immediately showing pregnant. On the 5th I used a clear blue digital which said not pregnant, but I know they need higher hgc.
Used another cbd yesterday (6th) also showing negative.
Today I pee'd in a tub and dipped in a cbd and a cheap lined test and both come up negative.
Had some symptoms and still no bleeding, and Dr still not called back.
Any ideas what is happening , is miscarriage possible? If it that is the case, I expected I would be bleeding by now.

Thankyou

Tests shouldn’t be looked at after the timeframe so that one was likely evap and digitals should work fine after missed period. It sounds like you’re not pregnant.

We did think down that route, apart from the 2nd test which was immediately positive, are the red dye tests common for false positive?

Dr has rang and suggested a cist, but again doesn't explain the positive.

@AlexG1991 depends on the brand. Clear blue are the worst for false positives but some pink dyes are bad for indents.

Sounds biochemical possibly.

Sorry what is an indent?
First 2 were supermarket own red dye (1 definitely pregnant)
Second 2 were clear blue digital (negative)
Then today a supermarket red dye and a clearblue digital (negative)
