Could I be ovulating or pregnant?

Patient: I have a 37 day cycle. I got my period Dec 1 and it ended Dec 5. I had unprotected sex on Dec 15, but we never reached orgasm as it hurt me. So all i probably came in contact was with precum. I’m not suppose to ovulate until Dec 24 (according to predictions). However I had clear eggwhite like mucus on December 13-14. Since December 23, my breasts hurt and I had cramps. Next period is expected to be January 7. Several questions:1) Is it possible to have an ovulation without eggwhite mucus?2) Or am I showing signs of pregnancy?
