I'm really confused. I'm 13 weeks pregnant and I've been suffering from hypermesis gravidarum. I am never sure if I'm hungry or it's just nausea/heartburn. The other issue is that I have no appetite because of the constant nausea and food aversions. I also have a hard time telling when I've eaten enough because it feels like the food sits in my throat and chest for hours after a meal until I puke it up. Generally I try to avoid vomiting and put up with the discomfort by going to sleep or I just allow it to come up and that's the only time I can feel comfortable. I have to vomit before I sleep or I can't get any rest from the pain. Anyone got any similar issues??
