I wasn't ovulating when I came off the pill after 10 years. Eventually saw a naturopath who put me on vitex (agnus cactus), and I ovulated the next month and bam, preggo!

Have you tried charting your temp to confirm whether you are ovulating? That's the only real way of knowing unfortunately, as cm and opks are not definite indicators.

Sorry you've had a tough time, it's stressful when your body doesn't behave as it should!

Good luck xx
