still having weird cm!

Emijean

soo I'm 7dpo and I've been having, like, white stretchy/sticky cm. it's not all that stretchy but it's really sticky and white. (my fertile mucus is clear) when I did a cm check it was so swollen that it was difficult to even get my fingers in (sorry, tmi I know) and when my hubby and I tried to do the deed it hurt too much. does anybody know what's going on?
