So nauseous i havnt been able to eat food. 😢

I can keep fluids down and some small snacks but if i eat heavy foods i puke. All i been eating for a month is pretzels and popsicles, small amounts of fruits and maybe some candies. I feel like i should be eating more for my baby, im 9 weeks, no bleeding or cramping but im still very worried im not getting enough food for the baby. I tried everything. Thinking about tryong b6 and unisom next. Has anyone tried this?
