Itching it’s so unbelievable I can’t handle this

Went to the GP earlier I am 16+4 with 3rd baby.

I am itching from head to toe and it’s driving me insane.

She took bloods there and then which in its self is a bit weird normally you get sent to a local clinic? And she then said you will either here from us tonight or tomorrow morning?? Well surgery closes at 6pm and doesn’t open til 8am so who is going to ring me and why? It was full blood count and liver function I am very nervous 😬 and can’t stop itching 😢
