bruise above blood draw site getting darker?

hello, I 25F, 140lbs, non smoker non drinker - got a routine blood draw last thursday the 23rd in the morning. seemed pretty regular, seemed like a normal amount of pinch if not her being a little rougher. next day or so I had a slight blue tinge above it (first pic: https://imgur.com/a/fbyI8ua ) and today it looks like this: https://imgur.com/a/y4U1Ji2

it’s been itchy I suppose but I have no other symptoms, it doesn’t even hurt. I’ve never had bruising from a blood draw and the only pictures I can find online are of extreme cases so I want to know how I’m looking.
