Not sure...

I am on CD 14, my cycle is normally 31 days but last month I was 3 weeks late before I started. Now I am having a really watery white discharge but it's thick and mucusy around cervix. I'm not sure when I will ovulate since I am on my first cycle with letrozole. We dtd on CD 7 and CD 10... I think I might have ovulated between 7-11... Now my cervix is rising and soft. What does it mean when you have alot of white discharge at around 3-7dpo? Could it be from the letrozole?
