Is my period abnormal?

My lmp was 12/23, when it was supposed to come 12/26. My period apps estimated my O date to be 1/3-1/6 but on 1/8 I felt what could have been ovulation cramps on my left side/ ovary as well as ewcm from 12/31-1/9. So could it be possible that since I may have ovulated 1/8 that my period should come a few days later to match my late ovulation date? I don't wanna be on my period on my birthday   lol
