Hi. I Took Coamoxiclav Because I Had My Third Molar

Hi. I took coamoxiclav because i had my third molar extracted. My dentist recommended that i should take the antibiotic for two weeks. I started taking it twice a day last July 22. I was supposed to have my period last July 26 and until now my mens still hasnt come. I always have regular period and its the first time that it got delayed. Is it possible that the antibotics affected my period? Thanks.
