When there is no bleeding, it means that the body quality is better, not affected by the drug, no side effects, it is also considered a normal performance. Not all women must have retractive bleeding after taking the drug, and when there is no bleeding, you need to wait patiently for the arrival of menstruation. If your period is delayed for a long time, you should buy a pregnancy test to rule out the possibility of pregnancy. Because the pill is not 100% contraceptive, there will be a certain chance of failure, so this time must also pay attention.
