I got a flu shot in may before i fell pregnant. i fell pregnant in july and was told its recommended to get a flu shot during 14 weeks gestation. should i still get a flu shot or can i get a top up flu shot?

I would not get it: The one you got in May should suffice.There is not adequate research on the safety of flu vaccine in pregnancy but there is evidence of a significant increased risk of miscarriage!
