toothache 18w5d HELP!

I ended up breaking a tooth a few days ago and it's turned into the most traumatic experience of my life. I believe it's infected now. I went to the emergency due to dentist being closed due to it being a weekend and Monday being a holiday. It's excruciating pain and I'm so worried about my growing baby. The doctor at the emergency room gave me Tylenol three to take every 6 hours along with the antibiotic Cephalexin. I'm scared to take any medication at all being a FTM. What are some natural remedies to help with the pain until I can get an appointment? And is my baby girl suffering in there due to the infection?! Please help I'm freaking out.
