Slapped cheek is very different to CP in pregnancy. Like I said earlier, if you have had CP as a child/adult and then get pregnant your baby will be fine - you have an immunity you pass through the blood - there is a slight risk baby could be born with CP if you catch v late in pregnancy but the risk is v v low. However, as Juliette pointed out slapped cheek can seriously damage a baby and can cause miscarriage - you would need to be tested for immunity (a lot of people will not be immune as it's not as common) as Juliette was. It's terrible that her GP did not know of the risk but I guess they don't know everything
Being the mother of a young child and also a baby I actually always research illnesses/stuff now myself before/after diagnosis as I don't always trust what I am told. Mainly because we've had the unfortunate situation of having both children in and out of hospital (most just outpatients but some inpatients) and I've come to realise medical opinion often contradicts itself!!!
On another note, (just in case someone reads the thread) you cannot catch shingles from CP, but CAN catch CP from shingles! Not sure why but that is a definite... And of course, shingles can come from an auto immune issue and so isn't 'caught' per se - it's normally in a person who is v stressed, run down, has a compromised immune system or something...
I only know all this because I've looked into it quite a few times with having young children myself I think I missed my vocation in life
