Ondansetron

I’m currently 15 weeks and I’ve had two separate doctors prescribe me Ondansetron for my morning sickness that’s been beating me up! I’m just worried about the side effects of the medicine. I feel horrible but I feel even worse (mentally) when I take it because it could harm my baby. I know the stigma that comes with the medicine but when I don’t take it, I can potentially end up in the hospital from dehydration because of how sick I become. Are there any moms out there that took this medication that are able to give me some advice on what to do? I just want a healthy baby and I’m so stressed because this is my first and I have no clue what to do!
