Hypermesis Gravidarum

Hey Ladies! So I've been in the hostpital for a week now because of Hypermesis Gravidarum and they have me on IV fluids. I feel hydrated but still can't eat. I don't have appetite because I'm scared when I nibble on something, I would throw it back up 😞. So they put a Picc Line in my upper arm and something about starting a TPN treatment through the PICC LINE (which is nutrition going through my body). Has any of u ladies had or has this condition?
