Da-Ying-35 is a short-acting contraceptive pill. Generally, as long as you take it orally for 21 days at the right time and in the right amount, you will get your period when you stop taking it for about 7 days. If you don’t get your period after taking TAIE-35, it means that it is not yet time, so it is recommended to observe for a few more days. If you are particularly anxious to bring your period quickly, it is recommended to go to the hospital for an ultrasound to see the thickness of the endometrium. If the thickness of the endometrium is above 0.8cm, it means that the endometrium is already thick and it is not recommended to take any oral medication etc. If the thickness of the endometrium is below 0.8 cm, it means that the endometrium is still relatively thin and oral medication can be taken to promote menstruation. For example, progesterone can be taken orally for 5 days, and after stopping the medication, menstruation will come in a week. Generally speaking, you will get your period after taking DY-35 orally, just for a short period of time. It is suggested that you can observe for 7-10 days, and then go for a check-up when it does not come.
