Patient's question:
Hello! I had my period on December 9th, and I used condoms throughout the time. At the end of the month, I took one birth control pill, and before taking it, a test strip showed negative. After that, I continued using condoms. As of January 17th, I haven’t had my period yet. From a cycle of 30 to 40 days, I tested three times—on day 31, day 36, and day 40—all showing negative. Now, my breasts are a bit tender. Can I rule out the possibility of pregnancy at this point? Thank you!First follow-up question: Hello!
Thank you for your response.
It’s been 40 days for me now. Is it necessary to test again with a test strip recently? Is it safe to eat...
Doctor's answer:
After taking birth control pills, vaginal bleeding is similar to menstruation, so many women worry whether it causes menstrual disorders. In reality, this is not the case. Since emergency contraceptives like Yuting are synthetic steroid hormones, taking them temporarily increases hormone levels in the human body. When this increase returns to normal, it causes a small amount of endometrial shedding in a woman's uterus, resulting in a small amount of bleeding. This is medically referred to as withdrawal bleeding, which is quite similar to "menstruation."
