Do you have to eat Yousiming for the first time on the first day of your visit

It is usually recommended to start taking Yousiming for the first time on the first day of menstruation. Yousiming is a short acting contraceptive pill that can be taken on the first day of menstruation to ensure contraceptive effectiveness. If the first day is missed, the medication plan should be adjusted under the guidance of a doctor. As a compound hormone contraceptive, the effectiveness of Yousiming is closely related to the start time of medication. Starting medication on the first day of the menstrual cycle can quickly stabilize the drug concentration and inhibit ovulation in a timely manner. At this time, the endometrium has just undergone shedding, and the regulation of endometrial growth by drugs is more synchronized, which can reduce the probability of breakthrough bleeding. Clinical data shows that the success rate of contraception for those who take medication on the first day of their menstrual cycle is close to the theoretical value, and hormone levels fluctuate less. Some women may not be able to take medication on the first day due to irregular menstrual cycles or unexpected situations. Starting within five days of menstruation and using the seven day barrier contraceptive method can still achieve reliable contraceptive effects. But if it exceeds the fifth day, you need to wait for the next cycle to start, otherwise it may lead to contraceptive failure due to ovulation already occurring. In special circumstances such as after abortion or the end of lactation, it is necessary to follow the doctor's advice and choose a more flexible medication timing, and adjust the plan based on ovulation monitoring if necessary.

Before using Yousiming, a gynecological examination should be conducted to rule out medication contraindications, and blood pressure and liver function should be regularly monitored during medication. It is recommended to match a balanced diet and keep regular work and rest, and avoid taking antibiotics or traditional Chinese patent medicines and simple preparations that affect the efficacy at the same time. If serious adverse reactions such as persistent headache, chest pain, or visual abnormalities occur, medication should be stopped immediately and medical attention sought. Long term medication users need to undergo annual breast and gynecological examinations to ensure medication safety.
