The 72-hour contraceptive pill normally charges around$20-40. Charges vary from place to place, so please take into account the local charges. Emergency contraceptive pills are generally used within 72 hours of unprotected sex, and the earlier you take them, the better the contraceptive effect and the higher the success rate. If a patient experiences a small amount of vaginal bleeding after taking the emergency contraceptive pill, there is no need to be overly nervous about this situation because the emergency contraceptive pill is levonorgestrel, and there will be a withdrawal bleeding after it acts on the endometrium. The emergency contraceptive pill cannot achieve a 100% success rate of contraception. If the patient has delayed menstruation, he/she needs to visit the hospital to check the blood HCG to rule out the possibility of unwanted pregnancy.
