cm type? please help!

Maggi

I am irregular (between 27-41 days) and only on CD 11 and getting this cm. have not had sex since Saturday night so it's not sperm. last month I didn't ovulate until CD 26 so I am hoping this means I have a normal cycle for once! however, my opks are still negative. any thoughts?! definitelt going to bd as soon as dd is in bed for the night lol I'm just hoping I didn't miss my window already!
