I really need help. I took one of the abortion pills today and I took an anti-bio pill. But I just threw up everything I ate today. I'm scared.?

Vomiting. Did you throw up the pills too? If you did, you might want to tell your doctor and be given another script for the pills.
Be seen. You can be assessed for stds, pregnancy, or other problems. You can also get anti nausea medication, as hormonal treatments often cause nausea.
