Looking for advice

I had a dye stealer test the day i was due AF so 4 weeks exactly. Im now 6 weeks 4 days. Friday 30th (morning wee) so 4/5 days ago i woke up and there was blood, was only the 1 time and wasnt much but i thought it was going to be the start of a miscarriage until no more blood came. I just had too wipe a few times until it went and it never went into a pad but this made me wait a couple days and test (just now) the first picture is at 4 weeks and the other is today. Is this a reelly bad sign? Thanks for looking.
