Everyone is very different! I have a very short luteal phase and have been known to ovulate on cd 9 or 10. So it is very important to watch your cycles to get your specific ovulation schedule. Keep in mind your cycle could vary monthly or could be very regular.
every women is different.. you need to find out how many days you have in your cycle period to period and then once you have that down... you can start temping to figure out when you are ovulating and also check your CM...
then it sounds like your not as familiar with your ovulation as you may thinkg if your not sure when ovulation begines.
if you have a 28 day schedual then you TYPICALLY, not always, ovulate around the 14-16 day after the start of your cycle.
yes there a chance. theres ALWAYS a chance
