The morning-after pill can only be used temporarily after sexual intercourse, at any time of the menstrual cycle, in cases where none of the contraceptive methods are used. When taken even during ovulation, or in other words, ovulation, when the probability of pregnancy is highest during the menstrual period, the high progesterone hormone in its content makes it difficult for the egg to be fertilized by sperm.

Levonorgestrel is a drug approved for use in emergency contraception applications by the World Health Organization for the prevention of pregnancy. This active substance is a synthetic derivative of the hormone progesterone and acts by binding to the receptors of this hormone in the body. In accordance with various physiological effects, it acts by preventing ovulation (ovulation) and fertilization or cracking of the egg that has already been secreted.

It is not recommended to use another progestin-containing contraceptive in the first 5 days after the use of emergency contraception drugs containing Ulipristal.

How Does the Morning-After Pill Provide Protection?
The morning-after pill, which should be taken as soon as possible after unprotected sex, prevents the occurrence of unexpected pregnancy thanks to the hormone progesterone in its content. For the formation of pregnancy, the sperm cell must fertilize the egg, which is waiting ready here when it reaches the fallopian tubes, one of the organs of the female reproductive system. A sperm cell that can remain viable in a woman's body for about 2 days can also create pregnancy by fertilizing an egg if ovulation occurs within 2 days after reaching the fallopian tubes. However, the morning-after pill taken after unprotected sex delays ovulation due to the high amount of hormones it contains. Even if the egg is fertilized by sperm in the fallopian tubes, with the use of the morning-after pill, it prevents the formation of pregnancy by preventing the thickening of the intrauterine wall, which allows the embryo to attach to the uterus.
The situations in which emergency contraception drugs can be used to prevent unwanted pregnancies can be summarized as follows:
* Condom rupture
* Skipping the regularly used contraceptive method
* Doubts about the adequacy of the current method of contraception, depending on other drugs used
* After unprotected sexual intercourse
* After sexual assault
The protection provided by the morning-after pill is considered to be quite high, especially in the pre-ovulation period, which is expressed as preovulation. The reason for this condition is that these drugs can also prevent the passage of sperm cells to the area where the egg cell is located by increasing the secretions in the cervix (cervix) area.
