My wife has gone through a lot in this first trimester. bright red bleeding, although not loads and was told the hospital were calling it a threatened miscarriage. however the 2 scans so far have not shown any probs whatsoever, especially the last scan. she is constantly sick or retching and her only food is burger king or cheese sandwiches (although she doesnt keep these down at times either). now she is losing weight... is all this normal? she still has a noticable bump and her breasts have started to grow
