Feeling worried...

My little man has had on going infections and kidney problems since he was 10 weeks old he now has his own team of consultants at great ormond street hospital in london and they are brilliant... it has been a tough few months for us emotionally and mentally but we decided this month that we really wanted to have another baby so we have been trying. But I completely forgot that our 6 month old has a scan just before Christmas which involves radioactive dye so if I was to fall pregnant I wouldn't be allowed anywhere near him for 24 hours and now I'm feeling guilty and it will break my heart not being with him for 24 hours 😔 and I know he will be so upset if I wasn't there 😔
