nausea/vomiting medication

is there ANYTHING i can take for vomiting that doesn’t require a prescription? i am still waiting on my Medicaid approval so i can’t go to a doctor yet but my morning sickness has turned severe. ive thrown up 7 times throughout the course of the day. i haven’t been able to keep any food down which is terrible because i have low blood sugar. last time i ate was around 6 and i threw it all up 30 minutes later and im still in and out of the bathroom even though there is nothing left in my system. i can’t live like this, someone please help 😭🤢 (im 6 + 4 if that matters)
