Really my whole question is in the title...I cant figure out why FF wont give me CH's I have clear fertile cm, that stopped the day I o'd and CLEAR temp rises and post O temps...? What do I need to change in my chart so that I get CH's? Its driving me nuts for some reason!

I know I o'd on CD15 I went and had an ultrasound that day and the follie was huge and about to pop, and I had clear O pains that day (along with the temp rise the next morning...which continues to rise)
