I seem to have the opposite problem at the moment and didn't get a positive OPK at all this month...... I either ovulated really early (CD10), missed the LH surge or didn't ovulate at all. I definately believe the change is due to the vitex though (whichever scenario is true!!) AS, would you try a break from it next month or carry on with 2 a day (am and pm)?
Thanks!
