As an emergency contraceptive pill, the first pill is usually taken within 72 hours after sexual intercourse, and the second pill is taken after 12 hours. The earlier you take it, the better the effect. Progesterone is the main ingredient of emergency contraceptives, which is basically the same as short-acting contraceptives and is suitable for women under the age of 40.

2. Short acting contraceptive pills:

Short acting contraceptives should be taken starting from the day of menstruation, one tablet per night for 22 consecutive days, and can be used for contraception for one month. The main function of short-term contraceptives is to inhibit ovulation and hinder the normal production of endometrium, which is suitable for women without basic diseases or diabetes.

3. Long acting contraceptive pills:

Generally speaking, after menstruation, taking one tablet on the fifth day and one tablet after 20 days can achieve effective contraceptive effects. Long term contraceptives mainly contain synthetic progesterone and long-term estrogen, which can inhibit ovulation and have a long-term contraceptive effect. Suitable for women who cannot place intrauterine devices and are unwilling to use other contraceptive methods.

However, general birth control pills are accompanied by instructions. If you are unsure when to take them, you can read them in detail or consult a doctor. If the delay in menstruation is too long after taking contraceptive pills, be careful to check for contraceptive failure.

Even if it is a sign of obesity, generally speaking, it only appears within one month of the first medication, and the body only adapts to the medication. If you still gain weight after a month, you may need to switch to a contraceptive pill or a hormonal medication.
