10DPO - three different tests!

Hi all!

So I am currently 10DPO but have been testing since 7DPO. On 7/8, I can see really faint lines but not too convinced. In the PM, I can see the same faint line. At 9DPO am, there’s the smallest glimmer of a line and in the PM the tiniest bit clearer. This morning I thought yes!! It’s gonna be a BFP. Wrong! One line is way way clearer (and it’s pink, not grey!) and two other tests completely negative. Can anyone help? I feel like I’m going crazy and I really don’t want to get excited! Surely FRER is really accurate so I should follow that instead of the cheap ones? Or could I have a bad batch of the cheap ones?

I have ordered some clear blue which arrive today. I had a dip in temp yesterday and this morning it’s back up!

8dpo: also a negative on FRER but faint line on E@H
