Does ovulating later change period due date?

I normally have 28-29 cycles and ovulate CD 14-15 but this time I ovulated like CD 17 (tracked with OVulation strips) so would that now make me due for my period CD 31? Im CD 28 today and no sign of period. Negative pregnancy test and 11 DPO. Hoping I will get a positive soon and AF wont come!! Let me know what you guys think?
