Patient's question:
Doctor: Hello!I had unprotected sex with my boyfriend on the 6th of this month. It happened once at midnight, once at noon, and I bought a box of Yuting from San Ye Pharmacy in the evening. The instructions said to take the second pill 12 hours later, but when I took the second pill, it was about three minutes late. I would like to ask you, what are the potential issues if I missed it by a few minutes? Will it affect the effectiveness of the pill? After taking it for a week, I noticed some breast tenderness, similar to the discomfort before my period. At the time, I thought it was just my period coming, but these symptoms disappeared after a few days.
Doctor's answer:
??????Hello, this can cause side effects such as nausea and vomiting after taking birth control pills. For some people, taking birth control pills can affect the normal menstrual cycle, which means the period may be delayed. Additionally, if the period is delayed by more than three days, you can take a pregnancy test to check for contraceptive failure. Try to reduce the use of birth control pills as much as possible.
