Hi, Im almost 10 weeks and my appetite still hasnt increased...its vanished somewhere else!
Its tough because you dont want anything, all I can suggest is what I am doing, and that is eating blandish food and trying to eat small amounts little and often
I wouldnt worry to much as I asked my midwife about this and its very normal, she suggested the above and to take a pregnancy vitamin. At this moment the baby takes very little from you nutrient wise so try not to worry
From what I hear, your appetite will come back with a vengance!!
