Daimler-35 is a short-acting contraceptive pill, which is mainly used clinically for contraception, regulating menstruation or treating hyperandrogenism due to polycystic ovary syndrome. The pill is usually started on the fifth day of menstruation and taken for 21 consecutive days, and menstruation usually occurs 3-7 days after stopping the pill. If you still don’t get your period on the ninth day after stopping the pill, you should rule out the possibility of pregnancy because although Da-Ying-35 is a short-acting contraceptive pill, the contraceptive effect does not necessarily reach 100%, so the possibility of pregnancy should be ruled out in this case. It is recommended to collect morning urine for early pregnancy test and not to drink too much water 2 hours before collecting morning urine to avoid false negative results due to dilution of urine. It is recommended that if you are not pregnant, go to the hospital for the appropriate tests.
