Two false positives?

[Gee1357]

I came off the combined pill June 27th and had a break bleed a few days after. I haven’t yet had a period and haven’t been tracking ovulation.
I did a Sainsbury’s pregnancy test mid-morning on Saturday that came up as positive very clearly.
I then did the other Sainsbury’s test Sunday evening and it came back as negative.
Monday I did a Clear Blue Ultra Ealry in the afternoon which was negative.
This morning I tested again with a Sainsbury’s test that came back as negative and again mid-morning which quickly came back as positive (photo attached).
Is it possible my HCG levels are just too low for the others to detect or are both of my positives false?

That looks like a dye bleed on the test.

I wouldnt take that as a positive.

That test looks a bit odd so I wouldn’t take that as a definite positive. Buy a digital with words. It saves analysing lines. If the test in the photo is positive it will definitely show up on a digital.

That’s a faulty test.

I agree with the above posters, that test looks invalid rather than positive. Another brand may be more reliable

That’s not a positive, it’s invalid
