On my period, but have faint line on pregnancy test

Ra

Hi all

Abit of a silly question maybe… & sorry for the TMI but I was due on my period on the 5th of July, but I came on the 8th of July. Usually my periods are like clock work and my cycle is every 28 days.

Out of curiosity I did a pregnancy test and 5 tests have came up with a really faint pink line straight away.

My period is like a normal period but I’m getting faint lines and I’m really confused as to how if I’ve got my period?

I have twins that are nearly 2 years old, don’t reckon it could be another multiple pregnancy at all?

Or just a miss understanding?

I’m so confused!

I’ve even edited the picture to see what it looks like in a negative contrast and I can still see the faint lines….

TIA x
