My sister realised she was pregnant in January, even though she was really late, but that meant that she had not realised all over Christmas. Her and her family do lots of food for the whole of the festive season so she was stuffing herself with pate, every kind of cheese you are not supposed to have and buckets of alcohol for about 3 weeks after she had already conceived!!! My neice, who will be 2 shortly, was one big healthy beautiful baby when she arrived and is now cute as a button and a clever cookie too so don't worry! Me on the other hand tried to cut things down when TTC and then stopped everything at all when got a BFP then had a MC at 11 weeks - not fair somehow.
