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.
Unless you have hit menopause it's the first few days of your period you are safe.
After menopause. Other than that, it's all a matter of when YOUR body ovulates. There is no single answer that fits all women.
Around the time at wich you ovulate ( release an egg ) usually this is a few days before the period.
During your period.
during the menstrual cycle
Menstruation occurs at the start of the menstrual cycle and normally lasts around a week, so menstruation would occur days 1-7 of the menstrual cycle.
If the egg is fertilized and results in pregnancy then the menstrual cycle stops. The menstrual cycle exists to allow pregnancy to occur, so when pregnant no need for it to continue.
They are entirely related. The previous answer that it's ultimately "God's will" and science is only "sort of" involved in fertility is complete nonsense; the entire menstrual process explains in detail when and how fertility occur. In other words, depending on where in your menstrual cycle you are, you will be more or less likely to become pregnant (less likely during your period and just after, more likely during ovulation).

it sure does occure late in many cases
Normal fluctuations occur as a result of puberty, the menstrual cycle, pregnancy, and menopause.
Sperm is the male sex cell that goes on to fertilize the egg in order for pregnancy to occur. The menstrual cycle is the female reproductive cycle, an egg is released during ovulation.
Menstruation is one of the phases of the menstrual cycle, whereas the menstrual cycle is the entire reproductive system. During the menstrual cycle an egg is released and to prepare for possible pregnancy the uterus lining plumps-up, if pregnancy doesn't occur the uterus lining sheds (menstruation) so it can start afresh again next cycle.
Most often missed periods occur during pregnancies.
