Cervical position?

Archana
Hi everyone, I know that you're only supposed to use CM and position for estimating ovulation, but I'm wondering about something weird. AF is due sometime this week for me, and for the past day or so, I'm getting a lot of watery CM, and my cervical position is bizarre. I can feel a large, firm, smooth mass, almost like my uterus is tilting forward and I'm feeling the back of it. I can't even get to my cervix because it's too far forward. Normally, feeling my cervix is very easy for me. Has anyone noticed this? Does it mean something?
