What does it mean?

Been ttc for 15 months now for my 3rd! This month my ovulation tests were positive for 4 days straight! Normally it's 2 days positive. Confused. Also my cervix is normally high and tilted back and almost always seems open and soft. But, the day after I think I ovulated this month, it was low and straight and open still! Then the next day it was high and tilted back again! What does this mean?
