Eating Habits

Sooo? For some reason the only thing that settles my tummy is chicken nuggets, French fries, and pineapples for right now. In no way that's healthy. But I have not been sick since. I also had a little chilli and I stay eating popsicles. Should I try to eat other things or should I just mainly focus on not being sick? I hate puking. My doctor prescribed me Zofran dissolvable tabs, but of course I'm a Google head and saw nothing good about those. And I have miscarried once before so I'm really just afraid to take anything. Thinking about just letting my body do what it's going to do. Any suggestions??
