Yes, it normally is so if you have a menstrual cycle of 28 day you ovulate on the 14th day. that means that if you have sex on day 10 of your cycle you can become pregnant because sperm can stay alive for about 4 days after being ejaculated into the woman. then the ovum lasts for about 2 days and disintegrates after day 16.
No, if a woman has no menstrual cycle then she cannot get pregnant. The menstrual cycle includes ovulation, no ovulation means no pregnancy. This is how hormonal Birth Control such as the combination pill works, it suppresses the menstrual cycles in order to stop ovulation to prevent unintended pregnancy.
The menstrual cycle is the reproductive cycle in human beings, and ovulation is one phase of the menstrual cycle. Each cycle a woman will ovulate and the uterine lining plups-up ready for possible pregnancy, but if she doesn't get pregnant then the uterine lining sheds (menstruation).
One of the methods to predict ovulation is calendar method. You just check you menstrual cycle and calculate ovulation. e.g. If you have a 28-day cycle, ovulation starts around the 14th day of the menstrual cycle.

Typically on day 14 of the menstrual cycle is when ovulation occurs - when an egg is released from the ovary. However everyone's menstrual cycles are different, if the cycle is longer it's likely ovulation occurs far later in the cycle than this.
Fertility is the ability to become pregnant. A woman is fertile when she is ovulating and for a few days before ovulation. Ovulation occurs in the middle of the cycle. For example, if woman has a 28 day menstrual cycle ovulation occurs at the 14th day of the cycle.
Ovulation
During ovulation
Ovulation is when your ovaries release an egg. Menstruation occurs when that egg is not fertilised and your menstrual cycle starts a new. Discharge is something you get throughout your entire menstrual cycle.
Generally speaking ovulation (fertile period) occurs two weeks before your period. The chances of pregnancy reach a maximum in the middle of the menstrual cycle, close to ovulation (if you have a 28-day menstruation cycle, the ovulation period is nearly the 14th day of the cycle. ) Cycle is counted from the first day of menses.
Between each ovulation, the lining the uterus is shed in the menstrual cycle. If the egg is fertilized, no further ovulation occurs and no menstrual shedding happens.
The Luteal phase in which ovulation begins.
Ovulation happens about day 14 of the cycle and if pregnancy doesn't happen within the 5-8 time frame the lining sheds and becomes the menstrual cycle.
