It is normal to have no withdrawal bleeding after taking the contraceptive pill. Because withdrawal bleeding from the uterus can only occur if there is a huge change in the level in the organism, some women experience no vaginal bleeding because the hormone level in the organism does not change much after taking the contraceptive pill. Most women do not experience withdrawal bleeding if they take the contraceptive medication regularly. The probability of adverse effects on the body, such as irregular vaginal bleeding, amenorrhea, obesity, abdominal pain, etc., may be relatively low with the use of contraceptive drugs. However, irregular use of the pill can lead to many adverse effects and can increase the probability of developing reproductive tumors. After taking the pill, it is necessary to observe whether there is any physical discomfort, and if there are serious discomfort symptoms, it is necessary to stop taking the pill in time.
