What are the causes of unexpected pregnancy?

The phenomenon of unexpected pregnancy can be said to happen very easily in life. Many times it is caused by not paying attention to the correct contraceptive measures during sexual life. In addition, the rupture of condoms during sexual intercourse and the use of antibiotics while taking birth control pills can easily affect the contraceptive effect.

(1) The condom breaks before sexual intercourse. About 2% to 5% of condoms will break during use. Typically, this is due to improper use. For example, not using hydrophilic lubricant, or small cuts caused by jewelry or nails. Condoms that are past their expiration date, not stored properly, or damaged before or after delivery can all cause condoms to fail to prevent pregnancy. If spermicides are used together with condoms, they can reduce unwanted pregnancies caused by condom failure.

(2) Taking antibiotics while using birth control pills. It has been scientifically proven that antibiotics can reduce the level of hormonal steroids, which are components of birth control pills, in the blood. Women who are accustomed to using oral contraceptives should use an alternative form of contraception when they start taking antibiotics.

(3) Naively believing that conception is not possible during menstruation or the safe period, and therefore attempting unprotected sex. Successful conception usually occurs in the middle of the menstrual cycle. However, some women get pregnant unexpectedly during their menstrual period or during their safe period. Believing that you cannot conceive during your menstrual period or safe period will increase the chances of an unwanted pregnancy. In addition, it also increases the possibility of contracting sexually transmitted diseases or other infections. Unless you only have one sexual partner for a long time, you must use condoms every time to reduce the risk of contracting sexually transmitted diseases and reduce the possibility of damaging fertility or even life.
