I had oral surgery with an anesthetic 2 days ago. I am on birth control and i'm not due for another week and a half. I am also taking amoxicillin for a tooth infection which I was told can affect birth control. Can any or all of this bring on my cycle so early? This has never happened to me.

Are you meaning that you have already gotten your period? When I saw the title of your thread it got me to wondering. I have a post just beneath yours about how my period has changed and about 3 weeks ago I had my wisdom teeth removed while under anesthesia...If anyone has info about this that would help, i'd like to know too-

I think it can - amoxicillin or any antibiotic upsets your system ...i dont know if you were unconcious with your surgery but i dont think this would affect your periods ...its prob the antibiotic ...which can affect birth control , you need to be taking EXTRA protection with birth control as well as taking the pill, until you have finished the antibiotics .
