Most women ovulate 14 days before their expected period but that is based on a 28 day cycle.
You ovulate after your period....No one but yourself can tell you when you are going to O, everyone is different....If you look at the top right of the page, were it says trackers and calculators, this are give you around when you should O.....Good Luck
