Towards the end of my AF, I feel more inclined  to sex and more slippery CM. I feel it strange coz, I want the exact same feeling towards my fertility periods and to be more exact during ovulation.   Rarely I am horny during ovulation. Ttc baby #1 and I really get afraid when I get horny towards the end of my AF and slippery CM. I could know 1-2 days advance that AF is popping sooner and it does.
