Menstruation, a woman's period.
Menstruation takes place about once a month during a woman's reproductive years. If woman has normal menstrual cycle she can get pregnant. If woman hasn't menstruation she hasn't possibility of conceiving/bearing children.
When the uterine lining sheds this is typically called menstruation. Although women on hormonal birth control will experience a faux period in the form of a withdrawal bleed.
Menstruation
A woman can get pregnant at any time but the best time is about 12 days after menstruation has finished up until it starts again
No, conception isn't possible during menstruation. During menstruation there is no egg present to be fertilised, although it's important to point out that a woman may still be fertile during menstruation: there may be fertile cervical mucus present, which can keep sperm alive in the vagina long enough so that there is still sperm present when a woman ovulates after menstruation.
No, a woman cannot still have menstrual periods after a hysterectomy. Menstruation is the shedding of the uterine lining, if there's no more uterus there's no more menstruation.
Yes, a woman can get pregnant immediately after her period. If she has a short menstrual cycle it is possible for her to ovulate directly after menstruation, or certainly she may be fertile directly after menstruation.
No, a woman cannot menstruate without a womb. Menstruation occurs when the lining of the uterus sheds each month through the cervix and vagina. Without a womb, there is no lining to shed, so menstruation cannot occur.
Conceive refers to an egg being fertilized, which then goes on to implant which means that a woman is pregnant. If a woman is pregnant then she will not menstruate, menstruation only occurs if conception doesn't occur.
