Fainter Pos than Original Pos??

Hi guys! I was due this week for period, did test Friday (03/02) just as a “I doubt it’s gonna be pos but I’ll test anyway” and ended up getting a faint pos, did a second a couple hours later to make sure and another faint pos.

I’ve spent the last 2 days just doubting these positives and waiting for the period to come so this morning (05/02) I decided to test again and got this? Is it just me or is the line getting even fainter…

I know if I am pregnant i would be suuuuuper early (est. 4 weeks) but now I’m worried I’m right and I’m not in fact pregnant and these are all just false positives…??

I do have a blood test on Monday (06/02) to confirm again buuuut I’m in my head..

PS. Still no sign of period, aside from faint cramping..??
