cancer and pregnant

Hi, any cancer patient here who has already ended chemo and got pregnant? Ive question, should i down with fever, sore throat and block nose, do you just see normal gp or went down A&E? I forgot to ask my gynae abt this. But as you know, during chemo times, if fever, has to come back to A&E. I hope someone can help. I wish there is a 24hours hotline to call and ask..?
