4 months pregnant, still losing weight.

Jasmine • Newly Married And Expecting A Second Child! 😍😍😍
I'm currently 16 weeks 5 days and I'm still losing weight. I have absolutely no appetite and my morning sickness has gotten worse. The doctors have tried Diclegis and Reglan but nothing is helping. I've tried everything. Any advice or natural remedies? I've also been suffering from dehydration. I really need help.
