Tooth ache and 8 weeks pregnant

Cynthia • 20, engaged and ttc.
Okay I have an infection in my back molar and it was supposed to get pulled. Then I found out I was pregnant. So I never went in to get it pulled. I took the amoxacillin that was prescribed and it didn't hurt for awhile. Now it's hurting again and I don't know what to do . It's soo awful . Kept me up all night long last night. Any suggestions ladies ?
