Unintentional weight loss during pregnancy

Hi. Has anyone else here lost a lot of weight? I am currently 14w5d. I’ve lost 25 lbs since becoming pregnant. It’s because I can barely eat anything. I am not vomiting. It is just the combination of eating induced nausea and that I can feel the food in my throat and gag reflex and it feels like it’s so hard for the food to go down my throat. Is that normal? My doctor said to take B6, Pepcid, and even Zofran but those are all treatment for nausea. I need something to help me with swallowing food. I’m worried I’m losing too much weight and it will negatively affect the baby. Every day is a huge struggle to get enough calories and I feel like I’m withering away. My mental health is declining because of this too.
