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.

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.
The citric acid cycle (also known as the Krebs cycle) produces the most NADH, generating 3 NADH molecules per cycle. The least ATP is produced in the electron transport chain, where each NADH molecule can produce up to 3 ATP through oxidative phosphorylation.

Each turn of the Kreb's cycle must regenerate oxaloacetate.
The temperature on the moons of Jupiter have very little effect on the female menstrual cycle.
The hormone that is least active while you are ovulating is progesterone. Progesterone is built up and reaches its high peak before your menstrual cycle.
The structure that least influences the human female menstrual cycle is the adrenal glands. While they produce hormones such as androgens and cortisol, their impact on the menstrual cycle is minimal compared to the primary roles of the ovaries and the hypothalamus-pituitary axis. The ovaries are crucial for hormone production and ovulation, while the hypothalamus and pituitary gland regulate the hormonal signals that control the cycle.
A woman is generally most infertile during the time outside her ovulation window, which typically occurs around the midpoint of her menstrual cycle. Specifically, she is least fertile during the menstrual phase (the first few days of her period) and the luteal phase after ovulation, when the egg is no longer viable. Additionally, fertility declines with age, particularly after the age of 35, making women less fertile overall in their late 30s and 40s.
no you still have to be protected. i cant remember but the monthly ovulation cycle either makes you most fertile or the least fertile when your on your period.... jenny x
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.
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.
Orientals are the least sexually active and least fertile. Blacks the most sexually active and most fertile. Whites are intermediate.
The safe period in reproduction refers to the time during a woman's menstrual cycle when she is least likely to conceive. This typically occurs just after menstruation and before ovulation, as well as after ovulation until the next period begins. It is based on the understanding of the menstrual cycle, where ovulation usually occurs around the mid-cycle. However, this method is not foolproof, as cycles can vary, and factors such as stress and health can influence ovulation timing.
Avoid pregnancy while taking misoprostol and for at least one month or one completed menstrual cycle after you have stopped treatment. Misprost is used to prevent ulcers, not pregnancy.

After a womb scrub, or dilation and curettage (D&C), it is generally recommended to wait at least one menstrual cycle before trying to conceive again. This allows your body to heal and for your menstrual cycle to regulate. However, it's essential to consult with your healthcare provider for personalized guidance based on your specific situation. They can provide tailored advice on when it's safe for you to attempt pregnancy again.
