Please help me figure out if this positive!

I’m so confused. This morning at like 3 am I took a cheap strip pregnancy test and it came up negative but I swore I saw a faint line. I took a photo and in the photo you can see the line but not in person Anyway, I took a test this morning with the same test and it came up positive after a few mins! It was quite clear and pink but then within about 5 mins the line completely disappeared! I’m so confused. I’m due my period in 5 days and I’m about 9dpo right now so it’s still early days but what was that? I have had quite a few symptoms already that aren’t normal for my cycle
