Massive tick

[challengeyourreality]

Never seen one like this, found it among our washing tonight. I always check the DC well so it must be from myself or DH or brought in from outside. Not sure how likely it is to find it's own way into the house. It's definitely an adult and was quite fast.
Wwyd? As I don't know if it ate from one of us and I'm worried about chances of Lyme disease. I also don't know what kind of tick it is as I don't recognise it -- it doesn't seem like the typical ones around here. Does anyone recognise it and if so could you name it please?

We had to remove a tick from our dog last week and it did not look like the picture.

@TheoriginalLEM thank you, it is a wodlouse spider and we have since found more.
My neighbour is a GP and also didn't recognise it as a tick so after some online investigation we concluded that it was a spider. Apparently it has a nasty bite so we are checking all clothes, bedding and seats before we use them.
Hopefully they were just some stray spiders from the garden and not living inside, doesn't seem typical for the species to live indoors.

You are very thorough op.

I did think about Woodlouse spiders, but the only ones I've ever seen have been massive. I suppose that must be a male instead, as the females are large enough for you to think 'What the actual FUCK is that?'.

I'm happy to be corrected (ticks are part of the spider family, by the way) as a spider is only going to bite you if you try your hardest to really, really piss it off and it's large enough to get a nip in, rather than something that exists purely to bite.

I suppose the type of GP that has experienced Lyme disease and patients with Lyme disease in an area that was until recently, claimed to be totally tick and LD free. Which isn't true, because I remember from being a small child having bites from things that left a bullseye rash on my legs and things my mother described as 'garden fleas' embedded in the cats' faces.
