Contact with Covid

Just wondering if anyone has any experience with this as I’m worrying my treatment will be cancelled

Yesterday (Friday) I was in my sisters when her husband got pinged and then LFT tested positive. I left straight away but had been there a few hours. 

I’m due to have blood tests and see my oncologist Monday and have my 5th cycle of chemo Wednesday and I’m worried it’s all gonna be cancelled because of chemo. 

However, is there a possibility that they will cancel it all anyway if I call Monday because it can take a few days after contact to test positive?

I just want this all over and don’t want chemo extended

Rudy1 , hope you’ve managed to get this resolved by talking to your team . Covid is the last thing you want to deal with alongside all the other things going on x
