21 dpo (9 days late)

I'm on a 28 day cycle, I took a pregnancy test on day 5 on being late came back negative. I'm having slight discomfort nothing major like period cramps feels like pressure of some sort. I bought an ovulation kit clear blue digital I recived my smiley face on the second of December. My husband and I had intercourse the day before and the two days after that hitting my ovulation day. The past few days I've noticed an increase in CM! I haven't taken a test I don't want to see that BFN before Christmas! Any input would be greatly appreciated thanks and Happy Holidays:-)
