Ovulation Help

Hey all,

Last month I started having positive opk's around day 19, with a blazing positive on CD21. I normally ovulate between day 19-21. With the blazing I had some cramping and heavy CM. This month, I'm on CD15 and still haven't had a positive but my body is producing heavier than normal CM (between creamy and watery, and a little stretchy) with some cramping. Should I stick with my opk's or listen to my body? I'm thinking I should probably start to BD every other day tonight for the next week right?
