Will Accidental Ingestion Of Plastic Fumes Affect Fetus During Pregnancy?

Im pregnant & just finished eating dinner and I may have ingested melted plastic fumes in my food . The oven was smoking badly while I was making it and I thought it was just food burning off. While eating my food there was stringy plastic in it. I looked in the oven and there was a melted plastic bread bag that melted and dripped into the food. Is this toxic to my unborn baby?? Thank you!
