I've just found out I'm about 5 weeks and this is my second baby. In the last week I've put on loads of weight and gone from a 14 up to an 18!! my boobs are like balloons and I look preg already - how do you hide it till 12 weeks? I've been off work on hols for 2 weeks and when I go back in tomorrow I'm worried people with guess. I don't want to tell people till after my scan really just in case - is this normal on the 2nd time round or am I just eating too many cakes !!
