Is this right ?

Aaliyah • Had my baby princess April 3 2016 ☺️ Had my baby prince March 14 2018
I went in to the ER because I was sooooo sick. Constant nausea and vomiting. They gave me an IV with Zofran & Sodium because I was a little dehydrated. They said that the babies heart rate was 97.. Is that too low ? I'm 5w 6 days
