Am facing big decision: after 2 IVF babies (first time round in each case) have now got accidentally pregnant - 6 weeks. Am 41 this year and have a 10 month old and a 3.5 year old. Am just back to work and getting life back to normal. Not at all sure what to do - but with 2 boys, might end up with a girl (which would be ace). What shall I do?
