Dental question when TTC


So I have to go to the dentist and I’m sure I will get novacaine when I go, is this okay for when I’m trying to get pregnant? My monthly isn’t due for another 9 days so I’m sure all is fine. I just want to make sure if I was pregnant, which is too early to tell anyway, if novacaine could affect my pregnancy. I had a miscarriage in September and were trying like hell over here and don’t want to mess with this one if I was. I’m sorry I’m being overly cautious lol 🙄
