hi, i really would wait till after the holiday to start trying, i mean you could get caught first time and im not too sure about the vaccinations but i know the morning sickness can be morning, all day and night sickness and the last thing you'd want to do is go on holiday when you feel like this, i had a terrible first 3 months, i couldnt eat a thing really, you immune system will be weak if you get sickness and are not eating properly, i really would wait just so you know everything will be ok
