One positive, one not positive - same morning wee??

[Llr2023]

Hi all - I took 2x clearblue ultra early tests this morning dipped in the same morning urine. The first came back pregnant, the next not pregnant. Is it because it’s really early and the second just didn’t pick up enough hcg - or what are the chances of a false positive? I know the answer is to test again so I’ve got some FRERs coming today - but wondered if anyone has had a similar experience? I’m either 9 or 10 DPO and not many symptoms.
Thanks so much xxx

test again that’s all there is for it

do you have pics?

I don’t really trust the clear blue ones. Also, it’s very early to test. I would wait a week and try again.

Here’s a pic!
