Hi Nicola
You're probably pretty tired anyway with a 5 week old baby! I haven't found the tiredness too bad (on Day 7), I have a 5 year old and it hasn't affected what I get up to with him, he's just at nursery until he starts school after the summer holidays. So I have him and two dogs to look after (my husband's away with work). Why don't you speak to your GP at your 6 week check and see what they say?
