In theory you're least fertile just before menstruation.
Take the average 28 day menstrual cycle:
A woman would ovulate around day 14 and produce fertile cervical mucus for up to a week beforehand, so the most fertile point would be between days 7-16 of the menstrual cycle. After ovulation there's no egg to fertilize, by the time you're due to menstruate any egg is long dead.
Unless you use Fertility Awareness Method you can't know when YOU are fertile or not, everyone has a different menstrual cycle and menstrual cycles can change all the time. You can't rely on an estimate or guessing fertile or infertile days based on previous cycles.

∙ 12y agoGoing by a 28 day cycle (yours may be longer or shorter):
Day 1 = 1st day of your period Day 5 = last day your period Day 12-16 = This is when you are most likely to conceive if you have sex about this time Day 14 = Ovulation date (approximately) Day 15-28 = Most women ovulate between 12-14 days before their next period
So approximately between day 6 and day 11 of your cycle is when you would be least likely to conceive. However you would have to be very exact and know your own cycle very well before you would be able to rely on this method.
Good luck.

You ended your period yesterday when do you start ovulating?
In the classic "text-book" menstrual cycle ( a 28 day cycle), ovulation should occur in day 14. The first day of the menstrual cycle is the day you start menstruating. But it may vary from women to women. If you what to know how your menstrual cycle behaves, the first thing you have to do is to document the start and end days of at least three concecutive cycles. Once you have determined how many days it takes in average, (starting from day one of mestruation to day one of the next) you may estimate that ovulation should be occurring just in the middle of the cycle... so it may vary from day 12 to 16 of the cycle (that's how the rythm method of contraception develops: no sex in those days, or use protection). Just remember that the first day of the cycle is the day you start menstruating.

What does the Moon have to do about the Menstrual Cycle?
The moon is believed to have an influence on women's menstrual cycles, not least of all because the average menstrual cycle syncs up with the phases of the moon. Women still use the moon to help regulate their menstrual cycles through using lunaception (sleeping in the dark all except for three days when you sleep in the light of the moon, which is when you'd want to ovulate - or artificial light if you want to try for a different cycle pattern). This is also why all the artificial light via computer screens and lighting in the home is believed to contribute to women's cycle problems.

When in the menstrual cycle is fertilisation likely to occur?
I would think when your period is the lightest. People say that having sex during your cycle is harder to get pregnant. So, when your almost done with your period I would think or when its almost over. If you don't wanna have sex on your period whenever your off is good. I hope this helps, sorry if it doesn't. The odds of being fertile during your menstrual cycle is very unlikely. You could say there's a 95% chance you are not fertile. Keep in mind, you are the LEAST fertile a week prior to menstruation and a week after. However, it is possible to conceive during this time. It's just highly unlikely.
