Teeth filling during first trimester

Lily
I had two teeh filling on Friday July24th and another two today. On Friday it went well, but today with first anesthesia I didn't really feel numbness and it was hurting so I asked the doctor to give me another shot of anesthesia and I felt something different all over my body like weakness. I am 6 weeks pregnant and now I am so worried if it's going to affect on baby's brain developing or anything else. My next visit at my doctor and first sonogram will be on August 6th. I am really worried now about This. Does anesthesia really effect on baby's brain or body developing or anything? I am so worried now and feel like I should call doctor and make the soonest appintment to discuss This matter with her. Any thoughts about you all ladies?
