Hi, my wife is 9 weeks pregnant and has developed a slight 'fishy' odour which is quite strong at times. is this a normal thing for some pregnant women? this is our first...my wife is 31, has had slight bleeding 2 weeks ago, her breasts have doubled almost :-) (!) and she has been sick/nauseous these past 2 weeks (and has had a craving at times for burger king!). please help!
