Missed period or late ovulation

Bri • Newly married and trying to conceive our first baby! My husband and I have been together for 11 years and are excited to see where life takes us!
Hi all! So my period was due dec 31st needless to say, AF has yet to show up.. I have been getting negative pregnancy tests since the 31st. This morning I decided to take an ovulation test just to see what it would say. & it was positive!! I used clear blue digital and had a solid smiley face. 
So am I ovulating super late or did I skip my period? Or is my body just wacky? Lol
Anyone else experience anything like this?
