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. I've put my test below, there is definitely a line you may just need to squint to see it, it was definitely there in person, my husband is normally dismissive of my line eyes but even he acknowledged this one!

All 4 tests were different brands

Can someone help? Have you been in a similar position?
