5 major side effects of birth control pills

　　Taking birth control pills will have more or less side effects. So, what are the specific side effects of birth control pills?

　　1. Facial pigmentation

　　Some women who take the drug for a longer period of time may develop butterfly spots on their cheeks, similar to those seen during pregnancy, which are pigmentation caused by estrogen. People who have pigmentation during pregnancy are more likely to develop it after using birth control pills, and it is related to sun exposure.

　　2. Vaginal bleeding

　　Many women will experience persistent spotting or breakthrough bleeding similar to menstrual flow while taking the medicine. This is related to missing a dose, taking the contraceptive pill late, or the contraceptive pill is not effective enough. If vaginal bleeding occurs in the first half of the menstrual cycle, it often indicates that the dose of estrogen is too small; if it occurs in the second half of the cycle, it indicates that the dose of progesterone is not enough to maintain Uterus Intima.

　　3. Oligomenorrhea or amenorrhea

　　Many female friends will report: After taking birth control pills, menstrual flow becomes less, or even amenorrhea occurs. What's going on? It turns out that birth control pills can cause underdevelopment of the endometrium and insufficient glandular secretion. Therefore, the endometrium cannot grow normally and becomes thinner, resulting in reduced menstrual flow. Due to the excessive inhibitory effect of birth control pills, some women do not experience withdrawal bleeding after stopping the drug and experience amenorrhea. 》》》》 female infertile4big sign
