Do you have high blood pressure?
Somethimes aspirin is prescribed for some mutations like MTHFR or others related to thrombophilia. So take it if he prescribed it or talk to another ob gyne. But if you have a mutation and you don't take it, your baby might ve at risk. I took it in my both pregnancies and my babies are just fine.
Why did your ob prescribe your aspirin? It's normally not recommended during pregnancy.
Aspirin is not safe during pregnancy tylanol is safe. You don't want to take ibuprofen
