What is Late Ovulation?

There are many phases in the menstrual cycle of women among this one of the phases is the phase of ovulation. During this phase of the cycle, an egg is released from both the ovaries and then this egg travels in the fallopian tube where it meets with sperm and fertilization takes place. After this zygote is formed which is implanted in the uterus and pregnancy took place. If in fallopian tube fertilization does not take place then the released egg from the ovaries is released from the uterus along with its lining during the menstrual cycle.


As it is well known that the time period of the menstrual cycle is 28 days, ovulation occurs around 14th day of this cycle. If a female is trying to become pregnant then she must conceive on the day of ovulation because this is the crucial time for fertilization. If a woman is having regular cycle then she must ovulate on the 14th day but it is studied that only 10% of the women have regular cycle means the cycle can range from 21 days to 35 days. So it is hard to find the time of ovulation for women having an irregular cycle and also challenging for her to find that when the conception is most likely to occur.

So late ovulation is said when the phase of ovulation occurs anytime after 21 days of the cycle.
