2 faint positive tests and the rest negative

[Amshw]

Hi, I’ve had 2 faint positive tests on different days but between and after these every other test has been negative

has this happened to anyone else, it’s so confusing

I had a few positives on those cheapie tests and wasn't pregnant, needed ivf in the end so no chance even a chemical pregnancy picking up hcg, they can be unreliable :( can you get a first response test as it detects extremely low hcg so is usually quite accurate.
