Thank you both it puts my mind more at ease....
Mention it to your doctor at your first appointment but as the above said the baby shouldnt be taking anything from you for another week or two. Everything should be ok, almost every pregnant women does something their not susposed to do before they know they are pregnant.
The baby doesn't take anything from you until 6-7 weeks so you should be ok. I would suggest mentioning it to your doctor at your first appointment, but I would suspect the s/he won't be concerned.
