Advice sorry a long post.

I am 11 weeks pregnant and had to get a tooth extraction today. They used a local anesthetic numbing shot. They did know i was pregnant and how far along i am. And the dentist said they usually like to wait til the 2nd trimester. But i needed it done. So i was wondering if anyone else had this done. But real question is. Is my baby okay and safe. Because now my stomach is cramping. But no bleeding or anything like that. Please comment.
