youngest has bug

im due to start chemo next week i think or even week after problem is my youngest has been sick tonight and although it cld just be one off im worried its a bug as im not so lucky to have a one off sick at nite from my kids. if it is a bug and i end up with it will they delay my chemo or should i get my partner to deal with it so that i have a chance of avoiding the bug. sill question i know

Not silly. However, you have at least 5 days so if you develop something, you can call the clinic and ask their advice. They will probably just postpone your first chemo for a week if you do get something.
