False positive, evap or positive?

[DBB2019]

I'm going through a bit of a strange situation and I'm driving my husband mad..
I had what thought was my period 4 days ago (it wasn't like my normal periods) I haven't been feeling right for about a week now and just how I felt when I was pregnant before which unfortunately ended in a MMC. I decided to take a pregnancy test yesterday and it was so faint, I'm not sure if it's an evap line or a positive but I took 2 blue dye and a digital and a pink dye. The 2 blue dyes came back as faint positives within the time you're meant to check it, the other 2 others came back as negatives. it was definitely there , my husband is normally dismissive of my line eyes but even he acknowledged this one!
All 4 tests were different brands but I've heard blue dye tests are notorious for being false positives
Can someone help? Have you been in a similar position?

Did you try a first response early detection?

Had a very similar experience- have tried clear blue and got a faint but definite BFP and since have negative with first respond- tried twice in the mornings. I’m going to try again next week but I think first response is supposed to be pretty accurate... maybe worth trying if you haven’t? Fingers crossed for you!

Hi both thanks for your responses I've never tried the first response ones so will give them a go in the future 😊

Took 2 tests this morning and both negative so I think it was a false positive!

Good luck X
