Can all of these be false??

[Rose38]

So last week I tested positive on Easy at Home. Day after the test was negative & I also tried a Clearblue which was negative. Just assumed a bad batch of tests on Easy at Home. Yesterday another positive on Easy at Home. Thought still a bad batch. Tried Clearblue and there was a weird semi second line.
Today I did Easy at Home and Wondfo both showing positive (see pic). Can they both be false? That would be weird right? Been experiencing boob pain & really bad headaches last few days too. Sometimes nausea but briefly. Usual pains you get before a period too.

Hi @Rose38 is your period late yet? It is strange to get a positive then negative then positive again a week later - unless maybe all different tests so varying strengths (maybe).

I've only had tests that get stronger and then fade away indicating a chemical preg.

The wondfo one is quite strong, I would go for another type of tests again and see what happens?
