I'm 5 weeks pregnant and with my last two (ended sadly in MC) I was constantly hungry. This time around I feel so nauseous and have absolutely no appetite - I'm having to force food down my neck but I'm only taking in about 1000 cals at most. This is coming from someone who usually considers an all-you-can-eat-buffet a light snack 
Is this normal and when do you start getting hungry again!? I'm taking parental vitamins and everything I am forcing is healthy. Not sure what else to do. Many thanks!
