Cervix/ovulation question

hello ladies!

I have taken clomid (I have polycystic ovaries) and at the fertility clinic they said I should be ovulating any day (that was 2 or 3 days ago) and on my ovulation calendar today is my strong green day, today I woke up and have pressure/kind of pain in my cervix area, I feel it when I walk or when I'm driving and go over a speed bump it's like a uncomfortable feeling and a bit painful, what does this mean? Has anyone else experienced this? Please help
