Boots 5 day early tests? Anyone used them? Do they always have an indent?

So I missed some mini pills over the last two weeks (I had alot going on couldn't get my prescription and I'm not even sure when what days I missed to be honest) anyway kast Wednesday I started having sore nipples and bad cramping, sore nipples now gone cramping lasted about 6 days stopped two days ago on Tuesday. I tested with two ICs as I felt rubbish both clear evaps after the time limit but this happened with both my previous pregnancies. I went to 3 different boots ans a superdrug to get some frer as their the only ones I really trust but couldn't find any. Have they stopped stocking them or something? Anyway. Left with two packs of boots 5 days early ones. Never used before. One yesterday and the day before had a clear indent line that darkened over the day. This mornings I could see a clear indent again at the 1/2 minute mark. I'll attach a picture but I doubt anyone will be able to see it. Anyway do these tests always have a clear indent? There's no colour so it's not a vfl but why are the indents like that?

Pic at 2 min mark. Anyone used these tests?not seen them before?

 

Didn't photograph very well but it looked like an indent to me

 

Grabbed some tests earlier tried a cheapy home bargains one step. Can see a shadow but I think I can literally always see a shadow on them if I'm completely honest now. They also had a supposedly early response test with apparently a sensitivity of 10mui. Ran into boots again now frer. Different boots this time. Is there a problem with supply or something atm? Picked just one pack of their early ones. I need to stop because I'm becoming obsessed again and we aren't even ttc right now.

Anyway dipped the supposed early one and a cheapie shadow on cheapie. Whisper on early response one so opened it up. (I know invalidates it but can see it clearer) I'll upload now. Obviously not fmu it's a 2 hour hold. Now th3 pic won't upload as their too big. Will have to crop

 

Took a boots one aswell. Faintest of the finest whisp. Looks like an indent again tho to me. Dissappears after a while rhen reappears after a few hours.

Pics are from around 5/6 minutes. So so faint. Hard to picture.

 

Definitely would have progressed if they were true positives. I'm under no illusions that their negative. They must have all been evaps/indents. Those tests aren't frers. Their boots ones. Can't seem to find frers anywhere atm. Their even sold out online.

Even though I know their not positive I still keep testing because you know may aswell finish the boxes I bought now. The two I dipped this morning had shadows on them too. Not sure why I keep getting evaps, like.i said I've had evaps before but not consistently like this. But I do know they would have definitely been having a clearer line by now. . But here we are 4 testa left. Wonder how long they will last lol
