HELP - Negative blood test but faint positives

[mumma21xx]

So I've been getting faint positive pregnancy tests on every single test i'm doing below 25 Imu (clear blue digital is negative) every single brand is coming up with a faint line and I have over 10 positives now even on internet cheapies. Had a blood test on Tuesday that came back

I had something very similar before my positive. Was in the end 2 weeks late and had a period!!! Before the period they took blood said it was negative. I then got a very strong positive 1 day after said period had finished. Midwife know one would believe me, until I had a bleed and had to have a early scan. They said wow you are a good 2 weeks ahead than we all thought. They thought I was 6 weeks and measured 8 weeks 2 days.
I’m now 33 weeks pregnant. So it does happen, just keep testing once a week and see what happens.
