The ingredients of birth control pills are mainly some normal hormones in the human body. Excessive use of birth control pills will cause an increase in the level of hormones in the body, thus inhibiting the occurrence of ovulation, which will have a great impact on the desire to get pregnant later. Long-term use of birth control pills can also cause endocrine disorders, irregular menstruation or amenorrhea. If you have chronic stomach problems, long-term use of birth control pills can also cause diarrhea, stomach pain and other discomforts that can aggravate stomach problems, or stomach pain after no stomach problems. So you should reduce the use of birth control pills, especially hormonal emergency contraceptives, which are more harmful to the body. In addition, sometimes contraceptive pills can show incomplete performance of contraception, and pregnancy occurs during the use of the pill.
